Research output: Contribution to journalArticlepeer-review


It is shown that a linear isometry of C(S) into C(T) is generated by a linear extension from S to a quotient space of T. A dual theorem is proved for a quotient map of C(S) onto C(T). An application of the first theorem and a modification of a theorem by Banach and Mazur provide a negative answer to a problem posed by Pelczynski.
