Sequential topological conditions in โ in the absence of the axiom of choice
Abstract It is known that โ assuming the axiom of choice โ for subsets A of โ the following hold: (a) A is compact iff it is sequentially compact, (b) A is complete iff it is closed in โ, (c) โ is a sequential space. We will show that these โฆ
