Maximizing Symmetric Submodular Functions

, 2016
Symmetric submodular functions are an important family of submodular functions capturing many interesting cases including cut functions of graphs and hypergraphs.

Jack–Laurent symmetric functions [PDF]

Proceedings of the London Mathematical Society, 2015
We develop the general theory of Jack-Laurent symmetric functions, which are certain generalisations of the Jack symmetric functions, depending on an additional parameter p_0.

On Symmetric Functions and Symmetric Functions of Symmetric Functions

The Annals of Mathematical Statistics, 1931
The study of symmetric functions is quite an old one. From the time of Girard (1629) even up to the present day this sub. ject has occupied the attention of many eminent mathematicians. The theory of the roots of algebraic equations in one or more variables has furnished the chief incentive for the development of the theory of symmetric functions ...

Combinatorics of k-shapes and Genocchi numbers [PDF]

Discrete Mathematics & Theoretical Computer Science, 2011
In this paper we present a work in progress on a conjectural new combinatorial model for the Genocchi numbers. This new model called irreducible k-shapes has a strong algebraic background in the theory of symmetric functions and leads to seemingly new ...

Fast Algebraic Attacks and Decomposition of Symmetric Boolean Functions

, 2009
Algebraic and fast algebraic attacks are power tools to analyze stream ciphers. A class of symmetric Boolean functions with maximum algebraic immunity were found vulnerable to fast algebraic attacks at EUROCRYPT'06. Recently, the notion of AAR (algebraic

Noncommutative Symmetric Hall-Littlewood Polynomials [PDF]

Discrete Mathematics & Theoretical Computer Science, 2011
Noncommutative symmetric functions have many properties analogous to those of classical (commutative) symmetric functions. For instance, ribbon Schur functions (analogs of the classical Schur basis) expand positively in noncommutative monomial basis ...

Stability properties of Plethysm: new approach with combinatorial proofs (Extended abstract) [PDF]

Discrete Mathematics & Theoretical Computer Science, 2015
Plethysm coefficients are important structural constants in the theory of symmetric functions and in the representations theory of symmetric groups and general linear groups.

Generalized Polarization Modules (extended abstract) [PDF]

Discrete Mathematics & Theoretical Computer Science, 2015
This work enrols the research line of M. Haiman on the Operator Theorem (the old operator conjecture). This theorem states that the smallest $\mathfrak{S}_n$-module closed under taking partial derivatives and closed under the action of polarization ...

Antipode formulas for some combinatorial Hopf algebras

, 2016
Motivated by work of Buch on set-valued tableaux in relation to the K-theory of the Grassmannian, Lam and Pylyavskyy studied six combinatorial Hopf algebras that can be thought of as K-theoretic analogues of the Hopf algebras of symmetric functions ...

Inclusion and Neighborhood on a Multivalent q-Symmetric Function with Poisson Distribution Operators

Journal of Mathematics
In this paper, by using Poisson distribution probability, some characteristics of analytic multivalent q-symmetric starlike and q-symmetric convex functions of order η are examined.
