Weak solutions via two-field Lagrange multipliers for boundary value problems in mathematical physics

Weak solutions via two-field Lagrange multipliers for boundary value problems in mathematical physics

A new variational approach for a boundary value problem in mathematical physics is proposed. By considering two-field Lagrange multipliers, we deliver a variational formulation consisting of a mixed variational problem which is equivalent with a saddle point problem. Thus, the unique solvability of...
