It is obtained the characterization of superreflectivity of Banach spaces in terms of convexity of the normalized based sequences. The new class of transitional functions is introduced and with its help is obtained that each continuous by Stallings function with closed graph is continuous. It is found necessary and sufficient conditions on topological space , which provide metrizability of some classes compact in . New topological games are introduced and with their help the discontinuity points set of -funсtions on products of some favourable and unfavorable spaces are studied.
