Characterizations of K- Semimetric Spaces

Characterizations of K- Semimetric Spaces

In this paper, we prove, for a space X, the following are equivalent: 1. X is a D1 space with a regular-Gδ-diagonal, 2. X is a D2 space with a regular-Gδ-diagonal, 3. X is a semi-developable space with Gδ (3) -diagonal, 4. X is a D1-space with a Gδ(3)-diagonal, 5. X is a D2 -space with a Gδ(3)-...
