A Remark on Multivariate Polynomial Interpolations

Abstract:

      C.de Boor and A.Ron in [1] proposed a map Θ → which associates eachfinite set Θ in Complex s-space with a polynomial space from which interpolation toarbitrary data given at the points in Θ is possible and uniquely. In this paper we describethe constructing methods of some other polynomial spaces Q from which interpolationat Θ is uniquely possible. This method is utilized to construct some nonconforming finiteelements (cf. [3,4]) with good convergence.
