## Abstract A new class of __C__^__n__^ continuous interpolations is presented. These interpolations consist of two or more Lagrangian interpolations blended by pseudo Hermitian interpolation. Using this class of interpolations a new __C__^__n__^ family of displacement type elements is developed. T
A two-level ΓΏnite element method is introduced and its application to the Helmholtz equation is considered. The method retains the desirable features of the Galerkin method enriched with residual-free bubbles, while it is not limited to discretizations using elements with simple geometry. The method
