The possible cardinalities of global secure sets in cographs

Comparing Cardinalities of Sets

Students often have motivational difficulty in accepting the definitions of comparing cardinalities of sets. The key to the application of the concepts lies in the so called SchröderBernstein theorem, the proof of which is often avoided due to its difficulty level. In this short article, we discuss the remarkable results around this theorem and finally give a very simple proof. On the way, we a...

Reconfiguring Independent Sets in Cographs

Two independent sets of a graph are adjacent if they differ on exactly one vertex (i.e. we can transform one into the other by adding or deleting a vertex). Let k be an integer. We consider the reconfiguration graph TARk(G) on the set of independent sets of size at least k in a graph G, with the above notion of adjacency. Here we provide a cubic-time algorithm to decide whether TARk(G) is conne...

Cardinalities of fuzzy sets with triangular norms

This paper presents a variety of cardinality concepts offered by cardinality theory of triangular norm-based fuzzy sets, including the scalar and the "fuzzy" streams.
