For a topological category/C over Set we prove that if a functor T: /C --+/C has a fixed cardinal a (i.e./or each object K with card (UK) = a we have card (UTK) <~ c~), then T has a least fixed point, and if T has a successive pair of fixed cardinals a and a +, then T has a greatest fixed point. Thi
