Sharp and unified error estimates for the nonsymmetric Nitsche method on convex polytopes
Gang Chen, Chaoran Liu, Yangwen Zhang
Nitsche's method weakly imposes Dirichlet boundary conditions, but its nonsymmetric variant has long shown a gap between theory and computation: the classical ~analysis under…

Optimal error estimation for the unfitted interface finite element method based on the non-symmetric Nitsche's methods
Gang Chen, Chaoran Liu, Yangwen Zhang
This paper establishes optimal error estimates in the for the non-symmetric Nitsche method in an unfitted interface finite element setting. Extending our earlier work, we giv…
