Abstract

Originally, exponentiable pretopological spaces X (i.e. −×X preserves quotients) were described by Lowen-Colebunders and Sonck as the finitely generated ones. Following a philosophy by I. M. James, a fibrewise notion of the latter property is introduced. Surprisingly or not, it turns out to characterize exponentiable maps.
