In this paper we study an open problem: Is it true that each homotopy domination of a polyhedron over itself is equivalence? Since every ANR has the type polyhedron, question related in obvious way to longstanding Borsuk's problem (1967) two ANR's dominating other have same type? The answer positive for all polyhedra (or ANR's) with polycyclic-by-finite fundamental groups, manifolds, and clearl...

in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
