Definition

  • A space X is cs-starcompact if for every open cover U of X, there exists a convergent sequence S of X such that imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20St%28S%2c%5cmathcal%7bU%7d%29=X%20%5c%5d%7d%25.png , where imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20%5cdisplaystyle%20St%28S%2c%5cmathcal%7bU%7d%29=%5cbigcup%5c%7bU%5cin%5cmathcal%7bU%7d:%20U%5ccap%20S%5cneq%5cemptyset%5c%7d%20%5c%5d%7d%25.png
