Discontinuity points of separately continuous mappings with at most countable set of values
UDC 517.51 We obtain a general result on the constancy of separately continuous mappings and their analogs, which implies the wellknown Sierpi´nski theorem. By using this result, we study the set of continuity points of separately continuous mappings with at most countably many values including, in...
