## Abstract For an arbitrary differential operator __P__ of order __p__ on an open set __X__ ⊂ R^n^, the Laplacian is defined by Δ = __P__\*__P__. It is an elliptic differential operator of order __2p__ provided the symbol mapping of __P__ is injective. Let __O__ be a relatively compact domain in _
