This note contains a corrected proof of the main result (which remains unchanged) from [K-T]. It was recently observed that an argument in a basic technical criterium has a gap. The first named author recently observed that the paper by Komorowski and Tomczak [K-T], contains a gap. Here we shall correct the formulation of a general result (Theorem 2.1 in… (More)

For a large class of Banach spaces, a general construction of sub-spaces without local unconditional structure is presented. As an application it is shown that every Banach space of finite cotype contains either l 2 or a subspace without unconditional basis, which admits a Schauder basis. Some other interesting applications and corollaries follow. 0… (More)

The talk presents some results appearing in papers [1, 2, 3]. We study lattice structures of rough approximations and rough sets determined by indiscernibility relations which are not necessarily reflexive, symmetric or transitive. Any map f between two complete lattices has an adjoint g, and the pair (f, g) is a Galois connection, if and only if f is a… (More)
