Abstract
In this paper, we study some properties of spaces having countable tightness and spaces having weakly countable tightness. We obtain some necessary and sufficient conditions for a space to have countable tightness. And we introduce a new concept of weakly countable tightness which is a generalization of countable tightness and show some properties of spaces having weakly countable tightness.
Keywords
countable tightness; sequential, strongly sequentially closed; sequentially closed; weakly countable tightness; k-spaces; and kq-spaces;
