Definition

A topological space is said to be strongly paracompact if it satisfies the following condition: every open cover has a star-finite open refinement.

Formalisms

Refinement formalism

In the refinement formalism, the property of being strongly paracompact has the following refinement formal expression:

Open Star-finite open

In other words, every open cover can be refined to a star-finite open cover.
