Exercises 4. a) If X is a topological space, its identity map Idx : XX, x→x is a homeomor- phism. b) A composition of homeomorphisms is a homeomorphism. c) Let E a normed space. If x E, the translation T, EE,yx+y is a homeomorphism. same if X € K \ {0}, the homothety Hx: E→E, y → Xy is a homeomorphism.
