R. F. Streater · Journal of Physics A Mathematical and General · 1980
Considers the covariant Laplacian in R n with Dirichlet boundary conditions on the boundary of a 'regular' region Lambda , in an arbitrary Yang-Mills field A of class C 1 . The author proves that its Green function G Lambda (A) obeys //G Lambda (A)//
