Definition Edit

  • Topological space X is said to be locally ν-compact space if every x in X has a ν-neighborhood? whose closure is ν-compact.

Property Edit

  • Every ν-compact space is locally ν-compact.
  • If f : (X,τ) → (Y,σ) is ν-irresolute?, ν-open and X is locally ν-compact,then so is Y.
  • ν-closed subset of a locally ν-Compact space is locally ν-Compact.
  • countable product of locally ν-Compact spaces is locally ν-Compact.
  • countable union of locally ν-Compact spaces is locally ν-Compact.
