Informationen zum Autor Adam Bobrowski is a professor and Chairman of the Department of Mathematics at Lublin University of Technology, Poland. He has authored over 50 scientific papers and two books, Functional Analysis for Probability and Stochastic Processes and An Operator Semigroup in Mathematical Genetics. Klappentext This book presents a detailed and contemporary account of the classical theory of convergence of semigroups. The author demonstrates the far-reaching applications of this theory using real examples from various branches of pure and applied mathematics! with a particular emphasis on mathematical biology. These examples also serve as short! non-technical introductions to biological concepts. The book may serve as a useful reference! containing a significant number of new results ranging from the analysis of fish populations to signalling pathways in living cells. It comprises many short chapters! which allows readers to pick and choose those topics most relevant to them! and contains 160 end-of-chapter exercises! so that the reader can test their understanding of the material as they go along. Zusammenfassung Written by a leading expert in the field! this book presents the classical theory of convergence of semigroups and then uses real examples to show how it can be applied to models of mathematical biology as well as other branches of mathematics.
