Hypercontractivity on the symmetric group [PDF]

open access: yesForum of Mathematics, Sigma, 2020
The hypercontractive inequality is a fundamental result in analysis, with many applications throughout discrete mathematics, theoretical computer science, combinatorics and more.

Centralizers of the infinite symmetric group [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We review and introduce several approaches to the study of centralizer algebras of the infinite symmetric group $S_{\infty}$. Our work is led by the double commutant relationship between finite symmetric groups and partition algebras; in the case of $S_{\

Symmetric group characters as symmetric functions [PDF]

open access: yesAdvances in Mathematics, 2015
We introduce a basis of the symmetric functions that evaluates to the (irreducible) characters of the symmetric group, just as the Schur functions evaluate to the irreducible characters of $GL_n$ modules.

Positivity of the symmetric group characters is as hard as the polynomial time hierarchy [PDF]

open access: yesACM-SIAM Symposium on Discrete Algorithms, 2022
We prove that deciding the vanishing of the character of the symmetric group is $\textsf{C}_= \textsf{P}$-complete. We use this hardness result to prove that the absolute value and also the square of the character are not contained in $\textsf{#P ...

The Valence-Bond (VB) Model and Its Intimate Relationship to the Symmetric or Permutation Group

open access: yesMolecules, 2021
VB and molecular orbital (MO) models are normally distinguished by the fact the first looks at molecules as a collection of atoms held together by chemical bonds while the latter adopts the view that each molecule should be regarded as an independent ...

Partition Algebras and the Invariant Theory of the Symmetric Group [PDF]

open access: yesAssociation for Women in Mathematics Series, 2017
The symmetric group \(\mathsf {S}_n\) and the partition algebra \(\mathsf {P}_k(n)\) centralize one another in their actions on the k-fold tensor power \(\mathsf {M}_n^{\otimes k}\) of the n-dimensional permutation module \(\mathsf {M}_n\) of \(\mathsf ...

The Round Functions of Cryptosystem PGM Generate the Symmetric Group [PDF]

open access: yesDes. Codes Cryptogr., 2018
S. S. Magliveras et al. have described symmetric and public key cryptosystems based on logarithmic signatures (also known as group bases) for finite permutation groups.In this paper we show that if G is a nontrivial finite group which is not cyclic of ...

NeutroAlgebra of Idempotents in Group Rings [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
In this paper, the authors study the new concept of NeutroAlgebra of idempotents in group rings. It is assumed that RG is the group ring of a group G over the ring R. R should be a commutative ring with unit 1.

The quasiinvariants of the symmetric group [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
For $m$ a non-negative integer and $G$ a Coxeter group, we denote by $\mathbf{QI_m}(G)$ the ring of $m$-quasiinvariants of $G$, as defined by Chalykh, Feigin, and Veselov.
