 Название: Turnpike Phenomenon in Metric Spaces
Автор: Alexander J. Zaslavski
Издательство: Springer
Год: 2023
Страниц: 365
Язык: английский
Формат: pdf (true), epub
Размер: 26.1 MB
In this book we study the turnpike phenomenon arising in the optimal control theory. To have the turnpike property means, roughly speaking, that the approximate solutions of the problems are determined mainly by the objective function and are essentially independent of the choice of interval and endpoint conditions, except in regions close to the endpoints. Special focus is placed on Turnpike results, in sufficient and necessary conditions for the turnpike phenomenon and in its stability under small perturbations of objective functions. The most important feature of this book is that it develops a large, general class of optimal control problems in metric space. Additional value is in the provision of solutions to a number of difficult and interesting problems in optimal control theory in metric spaces. Mathematicians working in optimal control, optimization, and experts in applications of optimal control to economics and engineering, will find this book particularly useful.

 Название: Stochastic Volatility and Realized Stochastic Volatility Models
Автор: Makoto Takahashi, Yasuhiro Omori, Toshiaki Watanabe ·

This treatise delves into the latest advancements in stochastic volatility models, highlighting the utilization of Markov chain Monte Carlo simulations for estimating model parameters and forecasting the volatility and quantiles of financial asset returns. The modeling of financial time series volatility constitutes a crucial aspect of finance, as it plays a vital role in predicting return distributions and managing risks. Among the various econometric models available, the stochastic volatility model has been a popular choice, particularly in comparison to other models, such as GARCH models, as it has demonstrated superior performance in previous empirical studies in terms of fit, forecasting volatility, and evaluating tail risk measures such as Value-at-Risk and Expected Shortfall. The book also explores an extension of the basic stochastic volatility model, incorporating a skewed return error distribution and a realized volatility measurement equation. The concept of realized volatility, a newly established estimator of volatility using intraday returns data, is introduced, and a comprehensive description of the resulting realized stochastic volatility model is provided. The text contains a thorough explanation of several efficient sampling algorithms for latent log volatilities, as well as an illustration of parameter estimation and volatility prediction through empirical studies utilizing various asset return data.

Название: Курс физики в 3 томах
Автор: Астахов А., Широков Ю.
Год издания: 1977 - 1983
Издательство: Главная редакция физико-математической литературы издательства "Наука"
Страниц: 1040
Формат: PDF
Размер: 27 Мб (+3%)
В первом томе изложены основы классической механики и кинетической теории материи.
Второй том курса посвящен физике неквантовых электромагнитных явлений. В нем затронуты также вопросы, последовательное объяснение которым дается только в квантовой теории (например, электропроводность, магнетизм вещества, дисперсия электромагнитных волн в веществе и ряд других). Эти вопросы рассмотрены с помощью классических моделей, в которых квантовая природа явлений феноменологически учтена исходными допущениями.
Третий том курса посвящен квантовой физике. | |

 Название: Linear Fractional Transformations: An Illustrated Introduction
Автор: Arseniy Sheydvasser
Издательство: Springer
Серия: Undergraduate Texts in Mathematics
Год: 2023
Страниц: 242
Язык: английский
Формат: pdf (true), epub
Размер: 52.6 MB
The principle aim of this unique text is to illuminate the beauty of the subject both with abstractions like proofs and mathematical text, and with visuals, such as abundant illustrations and diagrams. With few mathematical prerequisites, geometry is presented through the lens of linear fractional transformations. The exposition is motivational and the well-placed examples and exercises give students ample opportunity to pause and digest the material. The subject builds from the fundamentals of Euclidean geometry, to inversive geometry, and, finally, to hyperbolic geometry at the end. Throughout, the author aims to express the underlying philosophy behind the definitions and mathematical reasoning. This text may be used as primary for an undergraduate geometry course or a freshman seminar in geometry, or as supplemental to instructors in their undergraduate courses in complex analysis, algebra, and number theory.

 Название: Special Relativity for the Enthusiast
Автор: Thomas Strohm
Издательство: Springer
Год: 2023
Страниц: 347
Язык: английский
Формат: pdf (true), epub
Размер: 36.4 MB
This textbook introduces special relativity with a focus on a profound understanding of the physics behind the theory. The main part of the book is targeted to undergraduates, for physics education, for undergraduate students in natural sciences in general, and even to interested laypersons. To serve these target groups, the book uses only basic mathematics and, in contrast to many other introductions to special relativity, the book is based on a pedagogical approach that relies on geometry and space-time diagrams to make the surprising predictions of the theory particularly clear. Special relativity is a geometric theory, and space-time diagrams are an efficient and easily understandable way to comprehend its implications. The textbook, however, is also suitable for advanced students and enthusiasts that already learned the basics of the special theory of relativity and want to know more. Special digression sections provide plenty of interesting material.

This book entitled “Multivariate Calculus” is a compilation of all basic topics of Calculus and provides us with the tools to do so by extending the concepts that we find in Calculus, such as the computation of the rate of change to multiple variables, determination of the gradient of a multivariate function by finding its derivatives in different directions, extensive use in Neural Networks to update the model parameters etc. This book is primarily meant for undergraduate and post graduate students. The treatments of theories are a special feature of this book, which are presented in a systematic and interesting manner. Care has been taken to explain the subject matter in a clear and perspicuous style, so that even an average student can understand it independently. The purpose in writing this book has been to provide a development of the subject matter which is well-motivated, rigorous and up-to-date as best as possible.

 Название: Neuroscience For Dummies, 3rd Edition

A fascinating look at what's rattling around in your skull. Neuroscience For Dummies introduces you to the mind-boggling study of the human brain. It tracks to the content of a typical introductory neuroscience class at the college level - and it's perfect for anyone curious about what makes us tick. New technologies and an explosion of research have completely transformed our understanding of memory, depression, the mind-body connection, learning, and genetics. This updated edition - still in classic, beginner-friendly Dummies style - covers the latest research advances and technologies in the field of neuroscience. Put some knowledge about the brain into your brain. The central mystery about the brain is simply this: How can a bunch of interconnected cells make each of us what we are — not only our thoughts, memories, and feelings, but our identity. At present, no one can answer this question. Some philosophers think it is not answerable in principle. I believe we can understand how the brain makes us what we are. This book, while surely not containing the complete answer, points the way to what the answer looks like: In short, the brain is made of neurons, each of which is a complex little computer. Parts of the nervous system make suggestions to the rest of it about what you should do next.

Авторы данного учебного пособия, решили в краткой и доступной форме изложить основные понятия по механике студентам биологического факультета, учитывая и зная, что при изучении законов и физических явлений. эти студенты испытывают определённые трудности. Это, возможно связано с тем, что учебников по физике, написанных специально для биологов очень мало. В то же время, изложенный материал по физике, в указанных учебниках очень слабо отражает связь биологии с современной физикой, в них очень мало наглядных иллюстраций. | |
