Abstract

This paper discusses error estimates and convergence for interpolation by div-curl spline under tension of a vector field in the classical vectorial Sobolev space on an open bounded set with a Lipschitz-continuous boundary. A property of convergence is also given when the set of interpolating points becomes more and more dense.
