Abstract:
The multiplicative anomaly associated with the zeta-function regularized determinant is computed for the Laplace-type operators V 1=−Δ+V 1 and V 2=−Δ+V 2, with V 1, V 2 constant, in a D-dimensional compact smooth manifold M D , making use of several results due to Wodzicki and by direct calculations in some explicit examples. It is found that the multiplicative anomaly is vanishing for D odd and for D=2. An application to the one-loop effective potential of the O(2) self-interacting scalar model is outlined.
