Abstract

There are several generalizations of topological spaces which are "imaginary" in the sense of Martin Escardo. It is known for general reasons (see G. Rosolini "Equilogical spaces and filter spaces", Rend. Circ. Mat. Palermo, 64, 2000) that equilogical spaces are such an example. In this talk we give a direct and elementary proof of the fact that equilogical spaces satisfy Escardo's requirements for "generalized spaces".
