Permutation statistics related to a class of noncommutative symmetric functions and generalizations of the Genocchi numbers [PDF]
, 2009 International audienceWe prove conjectures of the third author [L. Tevlin, Proc. FPSAC'07, Tianjin] on two new bases of noncommutative symmetric functions: the transition matrices from the ribbon basis have nonnegative integral coefficients. This is done

Flavors of the Fubini-Bruhat Order [PDF]
, 2022 Thesis (Ph.D.)--University of Washington, 2022Fubini words are generalized permutations, allowing for repeated letters, and theyare in one-to-one correspondence with ordered set partitions.

Trace-positive polynomials and the quartic tracial moment problem Polynômes avec une trace positive et le problème quartique des moments traciaux [PDF]
, 2010 International audienceThe tracial analog of Hilbert's classical result on positive binary quartics is presented: a trace-positive bivariate noncommutative polynomial of degree at most four is a sum of hermitian squares and commutators.

Trace-positive polynomials and the quartic tracial moment problem [PDF]
, 2010 The tracial analog of Hilbert's classical result on positive binary quartics is presented: a trace-positive bivariate noncommutative polynomial of degree at most four is a sum of hermitian squares and commutators.This is applied via duality to ...

Word-representability of split graphs generated by morphisms [PDF]
, 2022 A graph G=(V,E) is word-representable if and only if there exists a word w over the alphabet V such that letters x and y, x≠y, alternate in w if and only if xy∈E.

Pattern avoidance in partial permutations [PDF]
, 2010 Motivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols $\pi = \pi_1\pi_2 ...

Encoding graphs by words and morphisms [PDF]
This thesis is related to encoding graphs by words, where we deal with so called word representation of graphs, relevant to them semi-transitive orientations, and more exotic ways to represent graphs via bijections with certain words and pattern-avoiding

Counting with symmetric functions [PDF]
, 2015 This monograph provides a self-contained introduction to symmetric functions and their use in enumerative combinatorics. It is the first book to explore many of the methods and results that the authors present. Numerous exercises are included throughout,

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...
