This book presents a mathematical theory of finite elements. Recent developments are covered in detail. Several reading paths are proposed, allowing for a readership with diverse interests. Engineers and applications-oriented researchers will find it useful. It can also be used as a graduate-level textbook.

Unique in that it manages to cover three different aspects of the finite element method in a single volume: the rigorous mathematical theory, applications, and practical implementations of the method

Autorentext

Alexandre Ern is Senior Researcher at Ecole des Ponts and INRIA in Paris, and he is also Associate Professor of Numerical Analysis at Ecole Polytechnique, Paris. His research deals with the devising and analysis of finite element methods and a posteriori error estimates and adaptivity with applications to fluid and solid mechanics and porous media flows. Alexandre Ern has co-authored three books and over 150 papers in peerreviewed journals. He has supervised about 20 PhD students and 10 postdoctoral fellows, and he has ongoing collaborations with several industrial partners. Jean-Luc Guermond is Professor of Mathematics at Texas A&M University where he also holds an Exxon Mobile Chair in Computational Science. His current research interests are in numerical analysis, applied mathematics, and scientific computing. He has co-authored two books and over 170 research papers in peer-reviewed journals.
