Abstract

We prove that a monomorphic functor F:CompCompF:Comp\to Comp with finite supports is epimorphic, continuous, and its maximal \emptyset-modification FF^\circ preserves intersections. This implies that a monomorphic functor F:CompCompF:Comp\to Comp of finite degree degFndeg F\le n preserves (finite-dimensional) compact ANR's if the spaces FF\emptyset, FF^\circ\emptyset, and FnFn are finite-dimensional ANR's. This improves a known result of Basmanov.
