Query: A BPHZ Theorem in Configuration Space   The concept of BPHZ renormalization is translated into configuration space.
After deriving the counterpart for the regularizing Taylor subtraction, a new
version of Zimmermann's convergence theorem by means of the forest formula is
proved. Furthermore, a sufficient condition on the algebraic decay of the
integrand is formulated such that the constant coupling limit exists in the new
setting.
