Sensitivities and block sensitivities of elementary symmetric Boolean functions

open access: yesJournal of Mathematical Cryptology, 2021
Boolean functions have important applications in molecular regulatory networks, engineering, cryptography, information technology, and computer science. Symmetric Boolean functions have received a lot of attention in several decades.

Symmetry Properties of Nested Canalyzing Functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Many researchers have studied symmetry properties of various Boolean functions. A class of Boolean functions, called nested canalyzing functions (NCFs), has been used to model certain biological phenomena.

Immaculate basis of the non-commutative symmetric functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We introduce a new basis of the non-commutative symmetric functions whose elements have Schur functions as their commutative images. Dually, we build a basis of the quasi-symmetric functions which expand positively in the fundamental quasi-symmetric ...

Branching rules in the ring of superclass functions of unipotent upper-triangular matrices [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
It is becoming increasingly clear that the supercharacter theory of the finite group of unipotent upper-triangular matrices has a rich combinatorial structure built on set-partitions that is analogous to the partition combinatorics of the classical ...

Weakly symmetric functions on spaces of Lebesgue integrable functions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
In this work, we present the notion of a weakly symmetric function. We show that the subset of all weakly symmetric elements of an arbitrary vector space of functions is a vector space.

NONCOMMUTATIVE SYMMETRIC FUNCTIONS ASSOCIATED WITH A CODE, LAZARD ELIMINATION, AND WITT VECTORS [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
The construction of the universal ring of Witt vectors is related to Lazard's factorizations of free monoids by means of a noncommutative analogue. This is done by associating to a code a specialization of noncommutative symmetric functions.

Linear Fractional Transformations of Nevanlinna Functions Associated with a Nonnegative Operator [PDF]

open access: yes, 2011
In the present paper a subclass of scalar Nevanlinna functions is studied, which coincides with the class of Weyl functions associated to a nonnegative symmetric operator of defect one in a Hilbert space.

Infinite log-concavity: developments and conjectures [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Given a sequence $(a_k)=a_0,a_1,a_2,\ldots$ of real numbers, define a new sequence $\mathcal{L}(a_k)=(b_k)$ where $b_k=a_k^2-a_{k-1}a_{k+1}$. So $(a_k)$ is log-concave if and only if $(b_k)$ is a nonnegative sequence. Call $(a_k)$ $\textit{infinitely log-

The Murnaghan―Nakayama rule for k-Schur functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We prove a Murnaghan–Nakayama rule for k-Schur functions of Lapointe and Morse. That is, we give an explicit formula for the expansion of the product of a power sum symmetric function and a k-Schur function in terms of k-Schur functions.

Quantum Symmetric Functions [PDF]

open access: yesCommunications in Algebra, 2005
We study quantum deformations of Poisson orbivarieties. Given a Poisson manifold $(\mathbb{R}^{m},α)$ we consider the Poisson orbivariety $(\mathbb{R}^{m})^{n}/S_{n}$. The Kontsevich star product on functions on $(\mathbb{R}^{m})^{n}$ induces a star product on functions on $(\mathbb{R}^{m})^{n}/S_{n}$.
