During this talk we will prove that if X and Y are first–countable perfect spaces, such that their free Abelian topological groups A(X) and A(Y) are topologically isomorphic, then X is a hereditary Baire space if and only if Y is also a hereditary Baire space.
This is a joint work with Mikołaj Krupski.
