The Inf-Sup Condition and Error Estimate of the Nitsche Method for Evolutionary Diffusion-Advection-Reaction Equations

The Nitsche method is a method of “weak imposition” of the Dirichlet boundary conditions for partial differential equations. The stability and error estimate of Nitsche’s method for evolutionary diffusion-advection-reaction equations are studied by the variational method, which is popular method for studying the elliptic problems. The inf-sup condition and Galerkin orthogonality give the optimal order error estimate in some appropriate norms under regularity assumptions on the exact solution.
