Idempotents in bicategories
Published online by Cambridge University Press: 17 April 2009
Abstract
It is shown that the category of fixed points of a left exact idempotent functor on a topos is again a topos. As well as a direct proof, a bicategorical proof is given which shows that the result only depends on certain bicategorical exactness properties.
