Frontiers in Mathematics is a journal with an advisory editorial board including prominent mathematicians from various institutions. The journal focuses on transport equations in biology, authored by Benoit Perthame from the Ecole Normale Superieure, France. The book is classified under mathematics and biology, with ISBNs and publication details. It includes a preface, chapters on population dynamics, transport equations, and mathematical tools, along with examples and exercises. The content covers topics such as structured population dynamics, population balance equations, chemotaxis, and general mathematical tools. The book aims to provide a mathematical analysis of biological models, emphasizing the structure and meaning of the models rather than just the technical details. It includes both examples without mathematical analysis and detailed proofs. The text discusses various types of partial differential equations, including parabolic and hyperbolic equations, and their applications in biology. The book also covers transport equations, kinetic equations, and their limits. The author thanks colleagues, collaborators, and students for their contributions to the work. The book is intended for mathematicians and is part of a series of lecture notes based on courses given at various universities.Frontiers in Mathematics is a journal with an advisory editorial board including prominent mathematicians from various institutions.
