Optimal codomains for the Laplace operator and the product Laplace operator

open access: yesJournal of Function Spaces and Applications, 2007
An optimal codomain for an operator P (∂) with fundamental solution E, is a maximal space of distributions T for which it is possible to define the convolution E*T and thus to solve the equation P (∂)S=T.

On odd Laplace operators [PDF]

open access: greenLetters in Mathematical Physics, 2002
We consider odd Laplace operators acting on densities of various weight on an odd Poisson (= Schouten) manifold $M$. We prove that the case of densities of weight 1/2 (half-densities) is distinguished by the existence of a unique odd Laplace operator depending only on a point of an ``orbit space'' of volume forms.

Functions of the Laplace-Beltrami operator [PDF]

open access: bronzeJournées équations aux dérivées partielles, 1996
Let \(M\) be a closed \(n\)-dimensional Riemannian manifold with metric \(g= (g_{ij})\) and let \(\Delta\) be the Laplace-Beltrami operator on \(M\). Consider further some additional symmetric linear differential operator \(\nu\) on \(M\) and let \(A_\nu\) be the square root of \(-\Delta+\nu\), defined in terms of pseudodifferential operators.

Laplace Operator and Polynomial Invariants

open access: bronzeJournal 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

Geometry of differential operators and odd Laplace operators [PDF]

open access: greenRussian Mathematical Surveys, 2003
We solve the following problem: to describe in geometric terms all differential operators of the second order with a given principal symbol. Initially the operators act on scalar functions. Operator pencils acting on densities of arbitrary weights appear naturally in the course of study.

Transmutation Operator Method for Solving Heat Conduction Problem [PDF]

open access: yesEPJ Web of Conferences, 2021
The transmutation operator method is extended to the case of functions of two variables. The transmutation operator flattens the function, i.e. the transmutation operator replaces a function with discontinuous partial derivatives on the coordinate axes ...

A characterization for $B$-singular integral operator and its commutators on generalized weighted $B$-Morrey spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2023
We study the maximal operator $M_{\gamma}$ and the singular integral operator $A_{\gamma}$, associated with the generalized shift operator. The generalized shift operators are associated with the Laplace-Bessel differential operator.
