Query: Relative partition function of Coulomb plus delta interaction   The relative partition function and the relative zeta function of the
perturbation of the Laplace operator by a Coulomb potential plus a point
interaction centered in the origin is discussed. Applications to the study of
the Casimir effect are indicated.
