 Название: Gauge Integral Structures for Stochastic Calculus and Quantum Electrodynamics
Автор: Patrick Muldowney
Издательство: Wiley
Год: 2021
Страниц: 382
Язык: английский
Формат: pdf (true)
Размер: 10.1 MB
A stand-alone introduction to specific integration problems in the probabilistic theory of stochastic calculus. Picking up where his previous book, A Modern Theory of Random Variation, left off, Gauge Integral Structures for Stochastic Calculus and Quantum Electrodynamics introduces readers to particular problems of integration in the probability-like theory of quantum mechanics. Written as a motivational explanation of the key points of the underlying mathematical theory, and including ample illustrations of the calculus, this book relies heavily on the mathematical theory set out in the author’s previous work. That said, this work stands alone and does not require a reading of A Modern Theory of Random Variation in order to be understandable. | |

 Название: Линейные дифференциальные уравнения на многообразиях
Автор: Крейн С.Г., Яцкин Н.И.
Издательство: Издательство Воронежского университета
Год: 1980
Формат: pdf
Страниц: 133
Для сайта: Mirknig.su
Размер: 33,53 Мб
Язык: русский
В монографии изучаются линейные дифференциальные уравнения на многообразиях с коэффициентами, принадлежащими алгебре Ли. Исследуются вопросы существования и единственности решений таких уравнений, а также свойства решений. Для вполне интегрируемых уравнений рассматривается важное отношение эквивалентности, связанное с линейной заменой неизвестной. Строится теория, включающая и обобщающая классические результаты типа теорем Ляпунова-Флоке к приводимости к постоянным коэффициентам и Перрона - о приводимости к треугольному виду. | |

 Название: Contemporary Scientific Realism: The Challenge from the History of Science
Автор: Timothy D. Lyons and Peter Vickers
Издательство: Oxford University Press
Год: 2021
Формат: PDF
Размер: 27 Мб
Язык: английский / English
Scientific realists claim we can justifiably believe that science is getting at the truth. However, they have faced historical challenges: various episodes across history appear to demonstrate that even strongly supported scientific theories can be overturned and left behind. In response, realists have developed new positions and arguments. As a result of specific challenges from the history of science, and realist responses, we find ourselves with an ever-increasing dataset bearing on the (possible) relationship between science and truth. The present volume introduces new historical cases impacting the debate and advances the discussion of cases that have only very recently been introduced. At the same time, shifts in philosophical positions affect the very kind of case study that is relevant. Thus, the historical work must proceed hand in hand with philosophical analysis of the different positions and arguments in play. It is with this in mind that the volume is divided into two sections, entitled "Historical Cases for the Debate" and "Contemporary Scientific Realism." | |

 Название: Optimal Enterprise: Structures, Processes and Mathematics of Knowledge, Technology and Human Capital
Автор: Mikhail V. Belov, Dmitry A. Novikov

In the modern world, most gross product is created within Enterprise firms, project programs, state agencies, transnational corporations and their divisions, as well as various associations and compositions of the above entities. Enterprises, being, on the one hand, complex, and, on the other hand, widespread systems, are the subject matter of cybernetics, system theory, operations research, management sciences and many other fields of knowledge. However, the complexity of the system obstructs the development of mathematically rigorous foundations for Enterprise control. Moreover, methods of operations research and related sciences, which are widely used in practice, provide optimization of the constituents of an Enterprise, without modeling it as a whole system. | |

 Название: Modern Applications of Graph Theory
Автор: Vadim Zverovich
Издательство: Oxford University Press
Год: 2021
Формат: True PDF
Страниц: 417
Размер: 10 Mb
Язык: English
Modern Applications of Graph Theory discusses many cutting-edge applications of graph theory, such as traffic networks, navigable networks and optimal routing for emergency response, placement of electric vehicle charging stations, and graph-theoretic methods in molecular epidemiology. Due to the rapid growth of research in this field, the focus of the book is on the up-to-date development of these applications and the mathematical methods used to tackle them. Ideal for researchers, engineers, transport planners and emergency response specialists who are interested in graph theory applications, Modern Applications of Graph Theory can also be used as teaching material. In addition to up-to-date descriptions of the applications, it includes extensive exercises and their solutions, mimicking practical, real-life situations. Furthermore, there is an introductory chapter, which provides an overview of basic applications and algorithms of graph theory. The book includes over 120 illustrations and tables. | |
