Zero-continuous functions on $K$-, $N$-, and complete spaces


andom best approximations, random fixed points Pap




Zero-continuous functions with the help of the family of ail the summable sequences - Theorem 3.1 and with its subfamilies - Theorem 3.4 and Theorem 3.6 are characterized. These results made it possible to obtain the continuity of summable and supersummable continuous functions.
