Query: Error analysis of Nitsche's mortar method   Optimal a priori and a posteriori error estimates are derived for Nitsche's
mortar finite elements. The analysis is based on the equivalence of the
Nitsche's method and the stabilised mixed method. The Nitsche's method is
defined so that it is robust with respect to large jumps in the material and
mesh parameters over the interface. Numerical results demonstrate the
robustness of the a posteriori estimators.
