Scalar characterization in Banach Jordan algebras

open access: yesUniversal Journal of Mathematics and Applications, 2018
Using a Diagonalization Theorem obtained when the spectrum is Lipschitzian, we extend a result of G. Braatvedt on scalar characterization in Banach algebras to Banach-Jordan algebras.

PA-CRT: Chinese Remainder Theorem Based Conditional Privacy-Preserving Authentication Scheme in Vehicular Ad-Hoc Networks

open access: yesIEEE Transactions on Dependable and Secure Computing, 2019
Existing security and identity-based vehicular communication protocols used in Vehicular Ad-hoc Networks (VANETs) to achieve conditional privacy-preserving mostly rely on an ideal hardware device called tamper-proof device (TPD) equipped in vehicles ...

Sturm-Picone Comparison Theorem of Second-Order Linear Equations on Time Scales

open access: yesAdvances in Difference Equations, 2009
This paper studies Sturm-Picone comparison theorem of second-order linear equations on time scales. We first establish Picone identity on time scales and obtain our main result by using it.

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.

Commutativity Theorems in Groups with Power-like Maps

open access: yesJournal of Formalized Reasoning, 2019
There are several commutativity theorems in groups and rings which involve power maps f(x) = xn. The most famous example  of this kind is Jacobson's theorem which asserts that any ring satisfying the identity xn = x is commutative.

Note on identities inspired by new soft theorems [PDF]

open access: yesJournal of High Energy Physics, 2016
The new soft theorems, for both gravity and gauge amplitudes, have inspired a number of works, including the discovery of new identities related to amplitudes. In this note, we present the proof and discussion for two sets of identities. The first set includes an identity involving the half-soft function which had been used in the soft theorem for one ...

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.

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

Eilenberg-Watts calculus for finite categories and a bimodule Radford 𝑆⁴ theorem [PDF]

open access: yesTransactions of the American Mathematical Society, 2016
We obtain Morita invariant versions of Eilenberg-Watts type theorems, relating Deligne products of finite linear categories to categories of left exact as well as of right exact functors.
