Since the early 1960s, the mathematical theory of variational inequalities has been under rapid development, based on complex analysis and strongly influenced b

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

Addressing various aspects of nonlinear partial differential equations, this volume contains papers and lectures presented at the Congress on Free boundary Prob

The material collected in this volume discusses the present as well as expected future directions of development of the field with particular emphasis on applic
