Abstract
We reexamine the two-point function approaches used to study vacuum fl uctuation in wedge-shaped regions and conical backgrounds. The appeara nce of divergent integrals is discussed and circumvented. The issue is considered in the context of a massless scalar field in cosmic string spacetime. [S0556-2821(98)03814-4].
