Baire space and second category extensions

Nearness structures induced by a T₁ second category or Baire space strict extension are characterized. Given a T₁ topological space it is shown that there exists a one-to-one correspondence between compatible nearness structures satisfying certain stated conditions and T₁ Baire space strict extensions of the space, up to the usual equivalence. A similar result is provided for second category T₁ strict extensions.
