Pták homomorphism theorem revisited

J. R. Ferrer, M. López Pellicer, L. M. Sánchez Ruiz (2000)

Czechoslovak Mathematical Journal

Similarity:

Rodrigues’ extension (1989) of the classical Pták’s homomorphism theorem to a non-necessarily locally convex setting stated that a nearly semi-open mapping between a semi-B-complete space and an arbitrary topological vector space is semi-open. In this paper we study this extension and, as a consequence of the results obtained, provide an improvement of Pták’s homomorphism theorem.
