Let A be an n × n matrix. The Hermitian parts of A are denoted by ℜ ( A ) = ( A + A ⁎ ) / 2 and ℑ ( A ) = ( A − A ⁎ ) / ( 2 i ) . The kernel vectors of the linear pencil x ℜ ( A ) + y ℑ ( A ) + z I n play a role for the inverse numeric

The goal of this article is to study some properties of generalized M−series introduced by Sharma and Jain in 2009. Here, we establish two theorems which provides the images of product of Srivastava’s polynomials and this M−series under the gen

In this article, we study the fundamental solution of the operator $$\left((\diamond+m^2)\left(\frac{\triangle^2+\boxdot^2}{2}\right)\right)^{k}$$ , iterated $k$ -times and is defined by ( \ref { odot }) ,where $m$ is a nonnegative real number, and $

This paper is dedicated to L p bounds on eigenfunctions of a Schrodinger-type operator ( − Δ g ) α / 2 + V on closed Riemannian manifolds for critically singular potentials V. The operator ( − Δ g ) α / 2 is defined spectrally in terms of the

This paper focuses on constructions of MDS self-dual codes from (extended) generalized Reed-Solomon (GRS) codes. Let $q = r^{2}$ be an odd prime power. We show that, there exists a $q$ -ary self-dual (extended) GRS code for each even length in the ra

In the present paper, we study a purely inseparable counterpart of Abhyankar’s conjecture for the affine line in positive characteristic, and prove its validity for all the finite local non-abelian simple group schemes in characteristic $$p>5$$ . T

We extend to arbitrary commutative base rings a recent result of Demeneghi that every ideal of an ample groupoid algebra over a field is an intersection of kernels of induced representations from isotropy groups, with a much shorter proof, by using t

Let A be an n-by-n matrix and M ( x , y , z ) = z I n + x ℜ ( A ) + y ℑ ( A ) , where ℜ ( A ) = ( A + A ⁎ ) / 2 and ℑ ( A ) = ( A − A ⁎ ) / ( 2 i ) . The inverse numerical range problem seeks a unit vector x corresponding to a given poi

This work studies the kernel of a linear operator associated with the generalized k-fold commutator. Given a set $\mathfrak{A}= \left\{ A_{1}, \ldots ,A_{k} \right\}$ of real $n \times n$ matrices, the commutator is denoted by$[A_{1}| \ldots |A_{k}]$

The congruence subgroup problem for a finitely generated group Γ and for G ≤ Aut ( Γ ) G\leq\mathrm{Aut}(\Gamma) asks whether the map G ^ → Aut ( Γ ^ ) \hat{G}\to\mathrm{Aut}(\hat{\Gamma}) is injective, or more generally, what its kern
