Abstract
A topological space is called strongly -metrizable if for an increasing sequence of closed metrizable subspaces such that every convergence sequence in is contained in some . If, in addition, every compact subset of is contained in some , , then is called super -metrizable. Answering a question of V.K.Maslyuchenko and O.I.Filipchuk, we prove that a topological space is strongly -metrizable if and only if it is super -metrizable.
