Abstract
The well-known Gitik–Shelah theorem (1989) touches the problem of existence isomorphisms between some quotient algebras.
In this paper, we study a relation between the existence of such isomorphisms and the existence of so-called Kuratowski partitions of adequate Baire spaces.
For this purpose, we give strictly combinatorial methods.
