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
In f 1 we introduce the concept of V-semi-identifying lift (V-semi-idt. lift) generalizing our concept of V-idt. lift [8], whose specific properties we want to discuss in another paper, and at the same time generalizing WYLER'S concept of V-proclusion pair [is]. We characterize those functors V : C
