Definition Edit

A subset K of a topological space X is called nearly weakly paracompact if for every cover C of X, there exists an open family B such that:

  1. B is point-finite;
  2. B refines C;
  3. K is contained in imgtex.fcgi?%5bres=100%5d%7b$%5ccup%5c%7b%5cmathrm%7bintcl%7d_X%20A:A%5cin%5cmathcal%7bB%7d%5c%7d$%7d%25.png.
