A Note on Four-Variable Reciprocity Theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We give new proof of a four-variable reciprocity theorem using Heine's transformation, Watson's transformation, and Ramanujan's 1𝜓1-summation formula. We also obtain a generalization of Jacobi's triple product identity.

Uniqueness and Liouville type results for radial solutions of some classes of k-Hessian equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
We establish a uniqueness theorem and a Liouville type result for positive radial solutions of some classes of nonlinear autonomous equation with the $k$-Hessian operator. We also give some interesting qualitative properties of solutions.

Scaling identities for solitons beyond Derrick’s theorem [PDF]

open access: yesJournal of Mathematical Physics, 2009
New integral identities satisfied by topological solitons in a range of classical field theories are presented. They are derived by considering independent length rescalings in orthogonal directions, or equivalently, from the conservation of the stress tensor. These identities are refinements of Derrick’s theorem.

Improved inclusion-exclusion identities via closure operators [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2000
Let (A v) v ∈ V be a finite family of sets. We establish an improved inclusion-exclusion identity for each closure operator on the power set of V having the unique base property.

A double bounded key identity for Goellnitz's (big) partition theorem

open access: yes, 2000
Given integers i,j,k,L,M, we establish a new double bounded q-series identity from which the three parameter (i,j,k) key identity of Alladi-Andrews-Gordon for Goellnitz's (big) theorem follows if L, M tend to infinity.

Constant term identities extending the 𝑞-Dyson theorem [PDF]

open access: yesTransactions of the American Mathematical Society, 1985
Andrews [1] has conjectured that the constant term in a certain product is equal to a q q -multinomial coefficient. This conjecture is a q q -analogue of Dyson’s conjecture [5], and has been proved, combinatorically, by Zeilberger and Bressoud [15].

On commutativity of one-sided s-unital rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
The following theorem is proved: Let r=r(y)>1, s, and t be non-negative integers. If R is a left s-unital ring satisfies the polynomial identity [xy−xsyrxt,x]=0 for every x,y∈R, then R is commutative. The commutativity of a right s-unital ring satisfying

A new application of Schrödinger-type identity to singular boundary value problem for the Schrödinger equation

open access: yesBoundary Value Problems, 2019
In this paper, we present a modified Schrödinger-type identity related to the Schrödinger-type boundary value problem with mixed boundary conditions and spatial heterogeneities.

Uniformly Primal Submodule over Noncommutative Ring

open access: yesJournal of Mathematics, 2020
Let R be an associative ring with identity and M be a unitary right R-module. A submodule N of M is called a uniformly primal submodule provided that the subset B of R is uniformly not right prime to N, if there exists an element s∈M−N with sRB⊆N.The set
