Query: Gas of wormholes in Euclidean quantum field theory   We model the spacetime foam picture by a gas of wormholes in Euclidean field
theory. It is shown that at large distances the presence of such a gas leads
merely to a renormalization of mass and charge values. We also demonstrate that
there exist a class of specific distributions of point-like wormholes which
essentially change the ultraviolet behavior of Green functions and lead to
finite quantum field theories.
