Applications of Homogenization Theory to the Study of Mineralized Tissue (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Homogenization is a fairly new, yet deep field of mathematics which is used as a powerful tool for analysis of applied problems which involve multiple scales. Generally, homogenization is utilized as a modeling procedure to describe processes in complex structures.

Applications of Homogenization Theory to the Study of Mineralized Tissue functions as an introduction to the theory of homogenization. At the same time, the book explains how to apply the theory to various application problems in biology, physics and engineering.

The authors are experts in the field and collaborated to create this book which is a useful research monograph for applied mathematicians, engineers and geophysicists. As for students and instructors, this book is a well-rounded and comprehensive text on the topic of homogenization for graduate level courses or special mathematics classes.

Features:

• Covers applications in both geophysics and biology.
• Includes recent results not found in classical books on the topic
• Focuses on evolutionary kinds of problems; there is little overlap with books dealing with variational methods and T-convergence
• Includes new results where the G-limits have different structures from the initial operators
