Laplace Operator and Polynomial Invariants

open access: yesJournal of Algebra, 1998
Assume \(A\) is a simple finite dimensional algebra over the field of complex numbers \(F\) and let \(G=\Aut A\) be the group of automorphisms of \(A\). (Note that \(A\) need not be associative.) The paper under review considers such algebras \(A\) that are equipped with a nondegenerate symmetric associative bilinear form \(\langle x,y\rangle\) that is

Some relations between fractional Laplace operators and Hessian operators

open access: yesBruno Pini Mathematical Analysis Seminar, 2011
After recalling the many representations of the fractional Laplace operator and some of its important properties, some recent results (proved in a joint work with Bruno Franchi and Igor Verbitsky) about the relations between the k-Hessian energy of the k-

On the fractional Laplace-Bessel operator

open access: yesAIMS Mathematics
In this paper, we propose a novel approach to the fractional power of the Laplace-Bessel operator $ \Delta_{\nu} $, defined as$ \Delta_{\nu} = \sum\limits_{i = 1}^{n}\frac{\partial^2}{\partial x_{i}^2} + \frac{\nu_i}{x_{i}}\frac{\partial}{\partial x_{i}}

Laplace operators on holomorphic Lie algebroids

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
The paper introduces Laplace-type operators for functions defined on the tangent space of a Finsler Lie algebroid, using a volume form on the prolongation of the algebroid.

On some possible applications of Laplace operator in a revolved coordinate system for numerical calculations

open access: yesТонкие химические технологии, 2013
The Laplace operator in a revolved coordinate system (the “revolved” Laplace operator) is introduced in numerical mesh method along diagonal lines. In this paper an attempt is made to use it for numerical solution of the two-dimensional Poisson equation.

The Application of Abstract Algebra in Operational Calculus

open access: yesFractal and Fractional
This paper is dedicated to elucidating the abstract algebraic structure of operational calculus theory. Based on abstract algebra and operational calculus, the operator algebra theory of Mikusiński has been revised. We restate the concept of Mikusiński’s

Hyperbolic double-complex Laplace operator

open access: yes, 2012
2010 Mathematics Subject Classification: 35G35, 32A30, 30G35. In this paper is introduced the hyperbolic double-complex Laplace operator. The hyperbolic decomplexification of the hyperbolic doublecomplex Laplace operator and its characteristic set is found.

Optical computation of the Laplace operator using phase-shifted Bragg grating.

open access: yesOptics Express, 2014
Diffraction of a 3D optical beam on a multilayer phase-shifted Bragg grating (PSBG) is considered. It is shown that the PSBG enables optical computation of the spatial Laplace operator of the electromagnetic field components of the incident beam.
