Maximum Principle for Variable-Order Fractional Conformable Differential Equation with a Generalized Tempered Fractional Laplace Operator

open access: yesFractal and Fractional, 2023
In this paper, we investigate properties of solutions to a space-time fractional variable-order conformable nonlinear differential equation with a generalized tempered fractional Laplace operatorby using the maximum principle. We first establish some new

Laplace Operators in Gamma Analysis [PDF]

open access: yes, 2016
Let $\mathbb K(\mathbb R^d)$ denote the cone of discrete Radon measures on $\mathbb R^d$. The gamma measure $\mathcal G$ is the probability measure on $\mathbb K(\mathbb R^d)$ which is a measure-valued L vy process with intensity measure $s^{-1}e^{-s}\,ds$ on $(0,\infty)$.

Defective Laplacians and paradoxical phenomena in crowd motion modeling

open access: yesComptes Rendus. Mécanique, 2023
In both continuous and discrete settings, Laplace operators appear quite commonly in the modeling of natural phenomena, in several context: diffusion, heat propagation, porous media, fluid flows through pipes, electricity....

A QUANTUM APPROACH TO LAPLACE OPERATORS [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2006
In this paper, a theory of stochastic processes generated by quantum extensions of Laplacians is developed. Representations of the associated heat semigroups are discussed by means of suitable time shifts. In particular the quantum Brownian motion associated to the Lévy–Laplacian is obtained as the usual Volterra–Gross Laplacian using the Cesàro ...

The formal Laplace-Borel transform of Fliess operators and the composition product

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The formal Laplace-Borel transform of an analytic integral operator, known as a Fliess operator, is defined and developed. Then, in conjunction with the composition product over formal power series, the formal Laplace-Borel transform is shown to provide ...

Imaginary powers of Laplace operators [PDF]

open access: yesProceedings of the American Mathematical Society, 2000
Let \(L\) be a second-order uniformly elliptic operator in divergence form on \(\mathbb{R}^d\). The authors show that the following inequality holds \[ C_1(1+ |\alpha|)^{d/2}\leq \|L^{i\alpha}\|_{L^1\to L^{1,\infty}}\leq C_2(1+ |\alpha|)^{d/2} \] for any \(\alpha\in\mathbb{R}\), where \(\|\cdot\|_{L^1\to L^{1,\infty}}\) is the weak type \((1,1)\) norm.

Problems with laplace operator on topological surfaces

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
This work highlights the problems related to the Laplace operator on topological surfaces such as Mobius strip, Klein bottle and torus. In particular, we discuss oscillations on the surface of the Mobius strip, eigenfunctions and eigenvalues of the ...

A Note on the Triple Laplace Transform and Its Applications to Some Kind of Third-Order Differential Equation

open access: yesAbstract and Applied Analysis, 2013
We introduced a relatively new operator called the triple Laplace transform. We presented some properties and theorems about the relatively new operator. We examine the triple Laplace transform of some function of three variables.

A note on maximal operators related to Laplace-Bessel differential operators on variable exponent Lebesgue spaces

open access: yesOpen Mathematics, 2021
In this paper, we consider the maximal operator related to the Laplace-Bessel differential operator (BB-maximal operator) on Lp(⋅),γ(Rk,+n){L}_{p\left(\cdot ),\gamma }\left({{\mathbb{R}}}_{k,+}^{n}) variable exponent Lebesgue spaces.

A natural Finsler-Laplace operator [PDF]

open access: yesIsrael Journal of Mathematics, 2013
We give a new definition of a Laplace operator for Finsler metric as an average with regard to an angle measure of the second directional derivatives. This definition uses a dynamical approach due to Foulon that does not require the use of connections nor local coordinates.
