Alon's Nullstellensatz for multisets

open access: yes, 2011
Alon's combinatorial Nullstellensatz (Theorem 1.1 from \cite{Alon1}) is one of the most powerful algebraic tools in combinatorics, with a diverse array of applications. Let $\F$ be a field, $S_1,S_2,..., S_n$ be finite nonempty subsets of $\F$.

Algebraic Verification Method for SEREs Properties via Groebner Bases Approaches

open access: yesJournal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013
This work presents an efficient solution using computer algebra system to perform linear temporal properties verification for synchronous digital systems. The method is essentially based on both Groebner bases approaches and symbolic simulation. A mechanism for constructing canonical polynomial set based symbolic representations for both circuit ...

FTheoryTools: Advancing Computational Capabilities for F‐Theory Research

open access: yesFortschritte der Physik, Volume 74, Issue 1, January 2026.
Abstract A primary goal of string phenomenology is to identify realistic four‐dimensional physics within the landscape of string theory solutions. In F‐theory, such solutions are encoded in the geometry of singular elliptic fibrations, whose study often requires particularly challenging and cumbersome computations.

The First Integral Method to the Nonlinear Schrodinger Equations in Higher Dimensions

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
The first integral method introduced by Feng is adopted for solving some important nonlinear partial differential equations, including the (2 + 1)‐dimensional hyperbolic nonlinear Schrodinger (HNLS) equation, the generalized nonlinear Schrodinger (GNLS) equation with a source, and the higher‐order nonlinear Schrodinger equation in nonlinear optical ...

On the natural nullcones of the symplectic and general linear groups

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract Consider a group acting on a polynomial ring S$S$ over a field K$\mathbb {K}$ by degree‐preserving K$\mathbb {K}$‐algebra automorphisms. Several key properties of the invariant ring can be deduced by studying the nullcone of the action, that is, the vanishing locus of all nonconstant homogeneous invariant polynomials.

New Exact Solutions of Some Nonlinear Systems of Partial Differential Equations Using the First Integral Method

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
The first integral method introduced by Feng is adopted for solving some important nonlinear systems of partial differential equations, including classical Drinfel′d‐Sokolov‐Wilson system (DSWE), (2 + 1)‐dimensional Davey‐Stewartson system, and generalized Hirota‐Satsuma coupled KdV system. This method provides polynomial first integrals for autonomous

On some matrix counting problems

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 6, December 2024.
Abstract We estimate the frequency of singular matrices and of matrices of a given rank whose entries are parametrised by arbitrary polynomials over the integers and modulo a prime p$p$. In particular, in the integer case, we improve a recent bound of V. Blomer and J. Li (2022).

On linear algebraic semigroups III

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 4, Issue 4, Page 667-690, 1981., 1981
Using some results on linear algebraic groups, we show that every connected linear algebraic semigroup S contains a closed, connected diagonalizable subsemigroup T with zero such that E(T) intersects each regular J‐class of S. It is also shown that the lattice (E(T), ≤) is isomorphic to the lattice of faces of a rational polytope in some ℝn.

On the existence of zero-sum subsequences of distinct lengths

open access: yes, 2012
In this paper, we obtain a characterization of short normal sequences over a finite Abelian p-group, thus answering positively a conjecture of Gao for a variety of such groups.
