Explicit expressions for fractional powers in modular products
Physical interpretation of divergent series values as vacuum energy
Abstract
We explore some axioms of divergent series and their relations with conformal field theory. As a consequence we obtain another way of calculating and for being a Dirichlet character. We hope this discussion is also of interest to physicists doing renormalization theory for a reason indicated in the Introduction section. We introduce a twist of the oscillator representation of the Virasoro algebra by a group of Dirichlet characters and use this to give a 'physical interpretation' of why the values of certain divergent series should be given by special L values. Furthermore, we use this to show that some fractional powers which are crucial for some infinite products to have peculiar modular transformation properties are expressed explicitly by certain linear combinations of 's for appropriately chosen 's, and can be understood physically…
