• Abstract

The single layer heat potential optential operator, K, arises in the solution of initialboundary value problems for the heat equation using boundary integral methods. In this note we show that K maps a certain anisotropic Sobolev space isomorphically onto its dual, and, moreover, satisfies the covercivity inequality $‹ K_{q,q} ›\geq c\|q\|^2$. We thereby establish the well-posedness of the operator equation $K_q=f$ and provide a basis for the analysis of the discretizations.
