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…

On the growth of the Möbius function of permutations

Vít Jelínek, Ida Kantor, Jan Kynčl +1

We study the values of the Möbius function of intervals in the containment poset of permutations. We construct a sequence of permutations of size for which $μ(1,π_…

On grounded L-graphs and their relatives

Vít Jelínek, Martin Töpfer

We consider the graph class Grounded-L corresponding to graphs that admit an intersection representation by L-shaped curves, where additionally the topmost points of each curve are…

On the structure of matrices avoiding interval-minor patterns

Vít Jelínek, Stanislav Kučera

We study the structure of 01-matrices avoiding a pattern P as an interval minor. We focus on critical P-avoiders, i.e., on the P-avoiding matrices in which changing a 0-entry to a…

Splittability and 1-amalgamability of permutation classes

Vít Jelínek, Michal Opler

A permutation class is splittable if it is contained in a merge of two of its proper subclasses, and it is 1-amalgamable if given two permutations and in , each with…

Hardness of Permutation Pattern Matching

Vít Jelínek, Jan Kynčl

Permutation Pattern Matching (or PPM) is a decision problem whose input is a pair of permutations and , represented as sequences of integers, and the task is to determine wh…
