Dual-primal mixed finite elements for elliptic problems (English)
0 references
The authors develop a new dual-primal mixed formulation for second-order elliptic problems. They use the approximation spaces such that trial functions are less regular than test functions. Some numerical experiments are carried out for the particular case of the Poisson problem.
