Dietrich Braess Book order

The book offers a comprehensive introduction to finite element methods, emphasizing updated content for research and practical applications. It features an in-depth discussion on saddle-point problems and nonstandard applications, alongside a complete examination of locking phenomena in elasticity. The author thoroughly addresses the numerical solution of elliptic partial differential equations within the framework of Sobolev spaces. It serves as an essential resource for graduate students lacking a strong background in differential equations, particularly in connecting mathematics and engineering through solid mechanics.

The exploration of nonlinear approximation problems, initiated by P.L. Chebyshev, reveals a deep connection to uniform approximation theory. Over the years, advancements have led to the development of best uniform approximation techniques using rational functions and polynomials. The distinction between linear and nonlinear approximation emerged in the 1960s, highlighting the need for nonlinear functional analysis and topological methods. This book delves into the application of these methods, including their relevance to linear approximation challenges, such as moment problems and polynomial interpolation.
