Abstract
We fix any pair consisting of a bicategory and a class of morphisms in it, admitting a bicalculus of fractions, i.e. a "localization" of with respect to the class . In the resulting bicategory of fractions, we identify necessary and sufficient conditions for the existence of weak fiber products.
