Abstract

This book covers an introduction to convex optimization, one of the powerful and tractable optimization problems that can be efficiently solved on a computer. The goal of the book is tohelp develop a sense of what convex optimization is, and how it can be used in a widening array of practical contexts with a particular emphasis on machine learning.The first part of the book covers core concepts of convex sets, convex functions, and related basic definitions that serve understanding convex optimization and its corresponding models. The second part deals with one very useful theory, called duality, which enables us to: (1) gain algorithmic insights; and (2) obtain an approximate solution to non-convex optimization problems which are often difficult to solve. The last part focuses on modern applications in machine learning and deep learning.A defining feature of this book is that it succinctly relates the “story” of how convex optimization plays a role, via historical examples and trending machine learning applications. Another key feature is that it includes programming implementation of a variety of machine learning algorithms inspired by optimization fundamentals, together with a brief tutorial of the used programming tools. The implementation is based on Python, CVXPY, and TensorFlow.This book does not follow a traditional textbook-style organization, but is streamlined via a series of lecture notes that are intimately related, centered around coherent themes and concepts. It serves as a textbook mainly for a senior-level undergraduate course, yet is also suitable for a first-year graduate course. Readers benefit from having a good background in linear algebra, some exposure to probability, and basic familiarity with Python.

Abstract

"Holographic Quantum Matter describes a new field that has emerged in the past decade at the interface of condensed matter physics and quantum gravity. Experimental discoveries in condensed matter have led to the identification of numerous materials--like high temperature superconductors (HTS)--in which the collective motion of electrons requires deeper understand of quantum effects at large length scales. HTS's act as a "strange metal" in which the charge and energy is not carried by quasiparticles. In the meantime, studies of quantum gravity using string theory led to a major breakthrough with the identification of a mathematical tool known as the holographic correspondence. The authors describe the developments that followed with the realization that states of quantum matter without quasiparticle excitations are precisely those that are efficiently described by the holographic correspondence. The book is addressed to graduate students in theoretical physics, especially those specializing in condensed matter, string theory, or quantum field theory. It presents the necessary background in the study of quantum matter and in string theory, so that students in both fields are apprised of recent developments in the other field. It connects this introductory discussion to what are the most important recent developments. It provides the tools and motivation for performing holographic computations. And it explains how the salient technical results from holographic studies have led to new insights into quantum matter"--

Abstract

The Yang-Baxter equation first appeared in theoretical physics, in a paper by the Nobel laureate C.N. Yang and in the work of R.J. Baxter in the field of Statistical Mechanics. At the 1990 International Mathematics Congress, Vladimir Drinfeld, Vaughan F. R. Jones, and Edward Witten were awarded Fields Medals for their work related to the Yang-Baxter equation. It turned out that this equation is one of the basic equations in mathematical physics; more precisely, it is used for introducing the theory of quantum groups. It also plays a crucial role in: knot theory, braided categories, the analysis of integrable systems, non-commutative descent theory, quantum computing, non-commutative geometry, etc. Many scientists have used the axioms of various algebraic structures (quasi-triangular Hopf algebras, Yetter-Drinfeld categories, quandles, group actions, Lie (super)algebras, brace structures, (co)algebra structures, Jordan triples, Boolean algebras, relations on sets, etc.) or computer calculations (and Grobner bases) in order to produce solutions for the Yang-Baxter equation. However, the full classification of its solutions remains an open problem. At present, the study of solutions of the Yang-Baxter equation attracts the attention of a broad circle of scientists. The current volume highlights various aspects of the Yang-Baxter equation, related algebraic structures, and applications.

Abstract

This open access book analyzes the dualism and inequality insofar as how it is manifested in interregional disparity and small enterprises. Using the case of Indonesia, the author considers how the general direction of policy should be to mitigate the effects of agglomeration forces leading towards concentration, and exploit the same forces by encouraging small businesses to operate in a cluster for collective action. The book addresses these issues by focusing on the role of interactions between policies and institutions, of which social capital is an important part.

Abstract

Electromagnetism plays a crucial role in basic and applied physics research. The discovery of electromagnetism as the unifying theory for electricity and magnetism represents a cornerstone in modern physics. Symmetry was crucial to the concept of unification: electromagnetism was soon formulated as a gauge theory in which local phase symmetry explained its mathematical formulation. This early connection between symmetry and electromagnetism shows that a symmetry-based approach to many electromagnetic phenomena is recurrent, even today. Moreover, many recent technological advances are based on the control of electromagnetic radiation in nearly all its spectra and scales, the manipulation of matter–radiation interactions with unprecedented levels of sophistication, or new generations of electromagnetic materials. This is a fertile field for applications and for basic understanding in which symmetry, as in the past, bridges apparently unrelated phenomena―from condensed matter to high-energy physics. In this book, we present modern contributions in which symmetry proves its value as a key tool. From dual-symmetry electrodynamics to applications to sustainable smart buildings, or magnetocardiography, we can find a plentiful crop, full of exciting examples of modern approaches to electromagnetism. In all cases, symmetry sheds light on the theoretical and applied works presented in this book.

Abstract

Arguments minimalistes est une présentation systématique et détaillée du Programme Minimaliste défini par Noam Chomsky il y a une vingtaine d’années et qui n’a cessé d’évoluer depuis. Le livre dresse un état des lieux de la théorie générative d’aujourd’hui, en prenant pour point de départ les textes de Chomsky lui-même. Le minimalisme inaugure une nouvelle façon de penser syntaxiquement et il vaut la peine d’examiner en détail les arguments que Chomsky invoque à l’appui de ce nouveau programme, qui met l’accent sur un ensemble de facteurs relativement ignorés dans les modèles précédents, mais qui doivent être, selon Chomsky, pris en compte prioritairement quand on cherche à construire une théorie du langage pleinement adéquate, allant au delà de l’adéquation explicative. Le fait que le langage soit en relation d’interface avec d’autres systèmes cognitifs auxquels il doit livrer des représentations lisibles, la nécessité de représenter la dualité de la sémantique, celle de linéariser les objets structuralement complexes produits par le mécanisme computationnel sont autant de dimensions qui contribuent nécessairement à façonner la Faculté de Langage et doivent intervenir dans la construction des grammaires. Cette synthèse, qui vise aussi à familiariser le lecteur avec les techniques d’analyse minimaliste, s’adresse aux étudiants avancés et aux linguistes confirmés, intéressés par la syntaxe et par les modèles formels en linguistique. Arguments minimalistes (Minimalist Arguments) is a state-of-the-art detailed and systematic introduction to the Minimalist Program, which was proposed by Chomsky twenty years ago and has been evolving ever since. The book reviews the current state of generative theory by taking Chomsky’s texts as a starting point. Minimalism introduces a new way of thinking syntactically and it is worth examining in detail the arguments that Chomsky puts forth in support of this new program, which places the emphasis on a set of factors that were…

Abstract

Critique et constructif à la fois, l'ouvrage critique le traitement classique des classifications dualistes (droite/gauche, masculin/féminin, noir/blanc, pur/impur...) et présente une perspective nouvelle à partir d'un exemple ethnographique africain très développé emprunté aux Nyamwezi et d'une reconsidération de cas classiques (africains, chinois, nord-américains). Dans l'essai de Robert Hertz au début de ce siècle, et de façon plus rigide encore de nos jours chez Rodney Needham et ses associés, le système classificatoire d'une société, si éloignée soit-elle du type moderne, est vu dans des catégories logiques qui relèvent de la pensée classique et moderne : non-contradiction, égalité des termes, rationalité du discours linéaire. On n'aboutit ainsi à des listes dichotomiques qu'arbitrairement et moyennant de nombreuses contradictions. A cette logique atomique Serge Tcherkézoff oppose une logique du tout, une logique hiérarchique qui, d'une part, privilégie le système idéologique et rituel global, de l'autre, se caractérise par la distinction de niveaux de représentation et d'expérience dont la gradation tolère et même prescrit la contrariété. A une plate dichotomie est ainsi substituée une figure multidimensionnelle, épaisse, vivante, dont l'unité est en même temps vigoureusement affirmée.

Abstract

This book presents collective works published in the recent Special Issue (SI) entitled "Multivariate Approximation for Solving ODE and PDE". These papers describe the different approaches and related objectives in the field of multivariate approximation. The articles in fact present specific contents of numerical methods for the analysis of the approximation, as well as the study of ordinary differential equations (for example oscillating with delay) or that of partial differential equations of the fractional order, but all linked by the objective to present analytical or numerical techniques for the simplification of the study of problems involving relationships that are not immediately computable, thus allowing to establish a connection between different fields of mathematical analysis and numerical analysis through different points of view and investigation. The present contents, therefore, describe the multivariate approximation theory, which is today an increasingly active research area that deals with a multitude of problems in a wide field of research. This book brings together a collection of inter-/multi-disciplinary works applied to many areas of applied mathematics in a coherent manner.
