This book describes the theoretical and computational aspects of the mimetic finite difference method for a wide class of multidimensional elliptic problems, which includes diffusion, advection-diffusion, Stokes, elasticity, magnetostatics and plate bending problems. The modern mimetic discretization technology developed in part by the...

This unique book is designed to provide the reader with an exposition of interesting aspects -- encompassing both rudimentary and advanced knowledge -- of oscillation theory of partial differential equations, which dates back to the publication in 1955 of a paper by Ph Hartman and A Wintner. The objective of oscillation theory is to acquire...

The theory of elliptic curves is distinguished by its long history and by the diversity of the methods that have been used in its study. This book treats the arithmetic theory of elliptic curves in its modern formulation, through the use of basic algebraic number theory and algebraic geometry. The book begins with a brief discussion of the...

If every communication network were to use a secure system based on encryption, then viruses, worms and hackers would have a very hard time. Unfortunately, this scenario does not reflect the reality of the Internet world today. However, with security issues becoming more and more important...
