Sequential spaces and their generalizations
by
Gino Tironi
Department of Mathematical Sciences, University of Trieste

Typical problems and results concerning sequential spaces and some of their generalizations, such as pseudoradial spaces, which were investigated in the last twenty years are reviewed. Some problems still open are pointed up. In particular, the problem of the productivity of pseudoradial spaces is considered from the beginning to the most recent results together with its connections to set theory.
