Uniqueness and convergence of the solution of nonconforming and mixed finite element methods with non-quasi-uniform partition are proven for nonselfadjoint and indefinite second-order elliptic problems under minimal regularity assumption. Moreover, uniform convergence of the solution of the nonconforming method is obtained. Meanwhile, a domain decomposition algorithm which suits to a non-quasi-uniform partition is proposed for nonconforming and mixed methods.
