Local Lagrange interpolations using bivariate \(C^2\) splines of degree seven on triangulated quadrangulations
Summary: A local Lagrange interpolation scheme using bivariate \(C^2\) splines of degree seven over a checkerboard triangulated quadrangulation is constructed. The method provides optimal order approximation of smooth functions.
