Some remarks on similar topologies / Pewne uwagi o podobnych topologiach
Journal Title: Bulletin de la Société des sciences et des lettres de Łódź, Série: Recherches sur les déformations - Year 2016, Vol 0, Issue 3
Abstract
Let T1, T2 be topologies defined on a set X. Assume that T1 and T2 are similar, that means the families of sets with nonempty interior in topological spaces (X; T1) and (X; T2) are equal. The aim of our paper is to check if the family of similar topologies forms a lattice and to examine the classes of continuous functions with similar topologies on the domain and range of the functions.

In this paper, we discuss the important contribution of Józef Puzyna into development of the integral equations theory and its meaning today. We mention also the role of Puzyna for creating the famous Lwów Mathematical S...
Representations and characters of Salingaros' vee groups of low order / Reprezentacje i charaktery grup vee Salingarosa niskiego rzędu
We study irreducible representations and characters of Salingaros' vee groups of orders 4, 8, and 16 as 2-groups of exponent 4. In particular, we construct complex irreducible group modules and explicit representations o...

On semiregularization of the density-type topologies / O semiregularyzacji topologii typu gęstościowego
We show that for several density topologies the semi-regularization of the topology is the coarsest topology for which the functions approximately continuous with respect to the topology are continuous. We show various m...
