A bijection between the set of nesting-similarity classes and L & P matchings
Megan A. Martinez, Manda Riehl
Matchings are frequently used to model RNA secondary structures; however, not all matchings can be realized as RNA motifs. One class of matchings, called the L P matchings, is…
Pattern Avoiding Linear Extensions of Rectangular Posets
David Anderson, Eric S. Egge, Manda Riehl +3
Inspired by Yakoubov's 2015 investigation of pattern avoiding linear extensions of the posets called combs, we study pattern avoiding linear extensions of rectangular posets. These…
Pattern Avoidance in Task-Precedence Posets
Mitchell Paukner, Lucy Pepin, Manda Riehl +1
We have extended classical pattern avoidance to a new structure: multiple task-precedence posets whose Hasse diagrams have three levels, which we will call diamonds. The vertices o…
Pattern avoidance in forests of binary shrubs
David Bevan, Derek Levin, Peter Nugent +4
We investigate pattern avoidance in permutations satisfying some additional restrictions. These are naturally considered in terms of avoiding patterns in linear extensions of certa…
On a pattern avoidance condition for the wreath product of cyclic groups with symmetric groups
Sergey Kitaev, Jeffrey Remmel, Manda Riehl
In this paper, we extend to a non-consecutive case, the study of the pattern matching condition on the wreath product of the cyclic group and the symmetric group initiated by the a…
New pattern matching conditions for wreath products of the cyclic groups with symmetric groups
Sergey Kitaev, Andrew Niedermaier, Jeffrey Remmel +1
We present several multi-variable generating functions for a new pattern matching condition on the wreath product of the cyclic group and the symmetric group. Our new pattern match…
