Abstract:A.~Chigogidze defined for each normal functor on the category {\sf Comp} an extension which is a normal functor on the category {\sf Tych}. We consider this extension for any functor on the category {\sf Comp} and investigate which properties it preserves from the definition of normal functor. We investigate as well some topological properties of such extension.
Keywords: Chigogidze extension of functors, 1-preimage preserving property
