Abstract: Variational inequalities have been playing a key role in
the modern scientific world. The theory of variational
inequalities provides a generalization of the theory of boundary
value problems and has applications in many fields like Applied
Mathematics, Mechanics, Theory of Control and so on. Unlike
variational equations, inequalities exhibit additional
singularities due to occurrence of free boundaries, which limit
the regularity of the solution. The study of computational methods
for variational inequalities thus offers more challenges. The
error analysis for the finite element methods of these problems
should also be derived under the limited regularity assumptions.
Adaptive finite element techniques are quite desirable for these
class of problems. We would like to discuss and exchange some of
the latest developments in the error analysis of finite element
methods for variational inequalities.
