## Sinopse

The book extensively introduces classical and variational partial differential equations (PDEs) to graduate and post-graduate students in Mathematics. The topics, even the most delicate, are presented in a detailed way. The book consists of two parts which focus on second order linear PDEs. Part I gives an overview of classical PDEs, that is, equations which admit strong solutions, verifying the equations pointwise. Classical solutions of the Laplace, heat, and wave equations are provided. Part II deals with variational PDEs, where weak (variational) solutions are considered. They are defined by variational formulations of the equations, based on Sobolev spaces. A comprehensive and detailed presentation of these spaces is given. Examples of variational elliptic, parabolic, and hyperbolic problems with different boundary conditions are discussed. Contents: Preface List of Symbols Classical Partial Differential Equations : What is a Partial Differential Equation? Classification of Partial Differential Equations Elliptic Equations Parabolic Equations Hyperbolic Equations Variational Partial Differential Equations: Lp-spaces The Sobolev Spaces W1,p Sobolev Embedding Theorems Variational Elliptic Problems Variational Evolution Problems Bibliography Index Readership: Graduate and post-graduate students as well as researchers who are interested in PDEs in both classical and variational approaches. Key Features: Consists of two parts, each self-contained, often discussed in separated textbooks in the literature. The foundation of the theories is presented with the properties and main results, most of them given with full proofs. Some theorems and proofs presented are not included in many PDE books but are vital foundational concepts Can be used as a textbook for one to three courses. It is detailed and yet, easy to read, thanks to many examples and remarks, and it is mathematically rigorous The detailed presentation of the book allows graduate and post-graduate students in Mathematics to be introduced to the world of second order PDEs. It can also be used by young researchers as a reference for variational second order PDEs This book is based on the long experience of the authors as researchers and teachers in the field of PDEs, teaching both in their home universities and in master or research schools in many countries abroad
