A space X is sequentially separable if there is a countable (Equation found) such that every point of X is the limit of a sequence of points from D. We present two examples of a sequentially separable space which is not selectively sequentially separable. One of them is in addition countable and sequential.

Abstract
A space X is sequentially separable if there is a countable (Equation found) such that every point of X is the limit of a sequence of points from D. We present two examples of a sequentially separable space which is not selectively sequentially separable. One of them is in addition countable and sequential.File in questo prodotto:
