Materials with Memory: Initial-Boundary Value Problems for Constitutive Equations with Internal Variables

This e-book contributes to the mathematical idea of platforms of differential equations such as the partial differential equations due to conservation of mass and momentum, and of constitutive equations with inner variables. The investigations are guided by means of the target of proving life and area of expertise, and are in response to the assumption of reworking the inner variables and the constitutive equations.

One-Dimensional Linear Singular Integral Equations: Volume II General Theory and Applications

This monograph is the second one quantity of a graduate textual content ebook at the sleek concept of linear one-dimensional singular vital equations. either volumes should be considered as special graduate textual content books. Singular necessary equations allure progressively more realization when you consider that this classification of equations appears to be like in different purposes, and likewise simply because they shape one of many few periods of equations that are solved explicitly.

Five Hundred Mathematical Challenges

This ebook includes 500 difficulties that diversity over a large spectrum of arithmetic and of degrees of trouble. a few are uncomplicated mathematical puzzlers whereas others are severe difficulties on the Olympiad point. scholars of all degrees of curiosity and talent can be entertained by way of the e-book. for plenty of difficulties, multiple answer is provided in order that scholars can examine the beauty and potency of alternative mathematical methods.
