Avoiding a pair of patterns in multisets and compositions

Vít Jelínek, Toufik Mansour, José L. Ramírez +1

In this paper, we study the Wilf-type equivalence relations among multiset permutations. We identify all multiset equivalences among pairs of patterns consisting of a pattern of le…

Non-uniform degrees and rainbow versions of the Caccetta-Häggkvist conjecture

Ron Aharoni, Eli Berger, Maria Chudnovsky +2

The Caccetta-Häggkvist conjecture (denoted below CHC) states that the directed girth (the smallest length of a directed cycle) of a directed graph on vertices i…

On factors of independent transversals in -partite graphs

Raphael Yuster

A -graph is a -partite graph with parts of order such that the bipartite graph induced by any pair of parts is a matching. An independent transversal in such a grap…

Higher Degree Davenport Constants over Finite Commutative Rings

Yair Caro, Benjamin Girard, John R. Schmitt

We generalize the notion of Davenport constants to a `higher degree' and obtain various lower and upper bounds, which are sometimes exact as is the case for certain finite commutat…
