ABSTRACT:

 A posteriori error estimators for the symmetric mixed finite
element methods for linear elasticity problems with Dirichlet and
mixed boundary conditions are proposed. Reliability and efficiency of
the estimators are proved. Finally, numerical examples are presented
to verify the theoretical results.
