Our Story


Book Description

The story of this family takes the reader through two hundred years of turbulent history and daily living. One member of the clan was Pálóczi Horváth Ádám, a staunch Hungarian patriot, collector of Hungarian folk songs at the turn of the 18th century, who believed that women should be entitled to an equal education with men, to the right to hold office and to have representatives in Parliament. His contemporary, Dukai Takách Judit was one of the first Hungarian female poets. Other illustrious members included writers, a diplomat, a state minister, and a mathematician. One fought in the Hungarian Revolution of 1848. Several died in the two world wars; many lived through the dismemberment of Hungary after World War I. The next generation made it through World War II, the Nazi occupation of the country, the Communist takeover of Eastern Europe, and the 1956 Hungarian Revolution. Many are still living in Hungary; others have left the country to seek better lives in England and America. Their personal stories bring alive the realities of life behind the headlines of history. The story of the family in the 20th century is told through the "portraits" of seven family members, spanning three generations. Pálóczi Horváth Lajos (author Dalma's father) was a writer, collector of folk songs (like Ádám) and champion of the rights of the peasants and industrial workers. He was a man of cosmopolitan education who spoke nine languages, but had a fierce loyalty to his country. He saw both Nazi Germany and Soviet Communism as equally dangerous to Hungary. After the Communist takeover of Hungary he was arrested on trumped up charges of subversion and served five years in prison. The freedom fighters of 1956 released him, but he did not leave his country even after the ruthless suppression of the 1956 Revolution. Hevesi Halász Laura, wife of Pálóczi Horváth Lajos and Dalma's mother, was born in the southern part of pre-World War I Hungary, an area assigned to Romania by the Treaty of Trianon. After World War I her widowed mother took the children to live in what was left of Hungary, and Laura lived through the privations and economic chaos caused by the dismemberment of the country. She was loyal to her husband, but in love with another man, Dálnoki Veress László, a Hungarian diplomat. During World War II Veress was charged by Hungary's Prime Minister to negotiate Hungary's surrender to the Allies. His "portrait" reveals the bittersweet complexities of this love triangle and its place in European history. Dalma's story shows how her life was shaped by these strong personalities and by the joys and cruelties of life in 20th century Europe and America. Together with her parents she made it through World War II and the siege of Budapest. For a month their house was in no man's land between the Russian and the German front lines. But the most traumatic part of the experience was the Russian occupation: for six weeks their home was an army hospital; the soldiers were the masters and the tenants were slaves obliged to obey their commands. Yet she also had the chance to learn much about the Soviet army because her father was the interpreter. In the years after 1945 hopes of a free country governed by free elections gradually faded. By 1947 the Communists were in control, arresting and imprisoning their opponents. Laura made the wrenching decision to leave Hungary with her daughter, and join Veress László, whom she later married. Dalma's story takes her through the challenges of starting a new life in England in the aftermath of World War II, preparing for exams, helping out at home while her mother and stepfather tried to make a living, and dreading news from Hungary where the Communists were gradually stifling all forms of freedom. She was 15 when she arrived in England. Seven years later she had a B.A. degree and teaching English in an English grammar school. But her challenges continued. After her marriage to Takác




Extreme Value Theory in Engineering


Book Description

This book is a comprehensive guide to extreme value theory in engineering. Written for the end user with intermediate and advanced statistical knowledge, it covers classical methods as well as recent advances. A collection of 150 examples illustrates the theoretical results and takes the reader from simple applications through complex cases of dependence.




Gorenstein Homological Algebra


Book Description

Gorenstein homological algebra is an important area of mathematics, with applications in commutative and noncommutative algebra, model category theory, representation theory, and algebraic geometry. While in classical homological algebra the existence of the projective, injective, and flat resolutions over arbitrary rings are well known, things are a little different when it comes to Gorenstein homological algebra. The main open problems in this area deal with the existence of the Gorenstein injective, Gorenstein projective, and Gorenstein flat resolutions. Gorenstein Homological Algebra is especially suitable for graduate students interested in homological algebra and its applications.

Applied Mathematics, Modeling and Computer Simulation


Book Description

The pervasiveness of computers in every field of science, industry and everyday life has meant that applied mathematics, particularly in relation to modeling and simulation, has become ever more important in recent years. This book presents the proceedings of the 2021 International Conference on Applied Mathematics, Modeling and Computer Simulation (AMMCS 2021), hosted in Wuhan, China, and held as a virtual event from 13 to 14 November 2021. The aim of the conference is to foster the knowledge and understanding of recent advances across the broad fields of applied mathematics, modeling and computer simulation, and it provides an annual platform for scholars and researchers to communicate important recent developments in their areas of specialization to colleagues and other scientists in related disciplines. This year more than 150 participants were able to exchange knowledge and discuss recent developments via the conference. The book contains 115 peer-reviewed papers, selected from more than 250 submissions and ranging from the theoretical and conceptual to the strongly pragmatic and all addressing industrial best practice. Topics covered include mathematical modeling and applications, engineering applications and scientific computations, and the simulation of intelligent systems. Providing an overview of recent development and with a mix of practical experiences and enlightening ideas, the book will be of interest to researchers and practitioners everywhere.

Yosida Approximations of Stochastic Differential Equations in Infinite Dimensions and Applications


Book Description

This research monograph brings together, for the first time, the varied literature on Yosida approximations of stochastic differential equations (SDEs) in infinite dimensions and their applications into a single cohesive work. The author provides a clear and systematic introduction to the Yosida approximation method and justifies its power by presenting its applications in some practical topics such as stochastic stability and stochastic optimal control. The theory assimilated spans more than 35 years of mathematics, but is developed slowly and methodically in digestible pieces. The book begins with a motivational chapter that introduces the reader to several different models that play recurring roles throughout the book as the theory is unfolded, and invites readers from different disciplines to see immediately that the effort required to work through the theory that follows is worthwhile. From there, the author presents the necessary prerequisite material, and then launches the reader into the main discussion of the monograph, namely, Yosida approximations of SDEs, Yosida approximations of SDEs with Poisson jumps, and their applications. Most of the results considered in the main chapters appear for the first time in a book form, and contain illustrative examples on stochastic partial differential equations. The key steps are included in all proofs, especially the various estimates, which help the reader to get a true feel for the theory of Yosida approximations and their use. This work is intended for researchers and graduate students in mathematics specializing in probability theory and will appeal to numerical analysts, engineers, physicists and practitioners in finance who want to apply the theory of stochastic evolution equations. Since the approach is based mainly in semigroup theory, it is amenable to a wide audience including non-specialists in stochastic processes.
