Let X be a topological space and let Y be its subspace.
Y is said to be 2-subparacompact if for every open cover U of X, there exists a family P of closed subsets in X such that P covers Y, P is a partial refinement of U and P is σ-discrete at Y.
- This is not a property for a topological space, but a subspace.
