Configurations related to combinatorial Veronesians representing a skew perspective
Agata Bazylewska-Zejer, Małgorzata Prażmowska, Krzysztof Prażmowski
A combinatorial object representing schemas of, possibly skew, perspectives, called {\em a configuration of skew perspective} has been defined in \cite{klik:binom}, \cite{maszko}.…
Hyperplanes in Configurations, decompositions, and Pascal Triangle of Configurations
Krzysztof Prażmowski
An elegant procedure which characterizes a decomposition of some class of binomial configurations into two other, resembling a definition of Pascal's Triangle, was given in \cite{g…
Configurations representing a skew perspective
Kamil Maszkowski, Małgorzata Prażmowska, Krzysztof Prażmowski
A combinatorial object representing schemas of, possibly skew, perspectives, called {\em a configuration of skew perspective} is defined. Some classifications of skew perspectives…
Relative complements and a `switch'-classification of simple graphs
Elżbieta Błaszko, Małgorzata Prażmowska, Krzysztof Prażmowski
In the paper we introduce and study a classification of finite (simple, undirected, loopless) graphs with respect to a switch-equivalence (`local-complement' equivalence of \cite{p…
Binomial partial Steiner triple systems with complete graphs: structural problems
Krzysztof Petelczyc, Małgorzata Prażmowska, Krzysztof Prażmowski
In the paper we study the structure of hyperplanes of so called binomial partial Steiner triple systems (BSTS's, in short) i.e. of configurations with points and $\b…
Multiplied configurations, series induced by quasi difference sets
Krzysztof Petelczyc, Krzysztof Prażmowski
Using the technique of quasi difference sets we characterize geometry and automorphisms of configurations which can be presented as a join of some others, in particular - which can…
Multiplied configurations characterized by their closed substructures
Krzysztof Petelczyc, Krzysztof Prażmowski
We propose some new method of constructing configurations, which consists in consecutive inscribing copies of one underlying configuration. A uniform characterization of the obtain…
