This advanced graduate-level text examines variational methods in partial differential equations and illustrates their applications to a number of free-boundary

Many phenomena of interest for applications are represented by differential equations which are defined in a domain whose boundary is a priori unknown, and is a

This book is concerned with several elliptic and parabolic obstacle-type problems with a focus on the cases where the free and fixed boundaries meet. The result

For the past several decades, the study of free boundary problems has been a very active subject of research occurring in a variety of applied sciences. What th
