Fractional Operators Associated with the ք-Extended Mathieu Series by Using Laplace Transform

Advances in Mathematical Physics, 2021
In this paper, our leading objective is to relate the fractional integral operator known as Pδ-transform with the ք-extended Mathieu series. We show that the Pδ-transform turns to the classical Laplace transform; then, we get the integral relating the ...

LORETA With Cortical Constraint: Choosing an Adequate Surface Laplacian Operator

Frontiers in Neuroscience, 2018
Low resolution electromagnetic tomography (LORETA) is a well-known method for the solution of the l2-based minimization problem for EEG/MEG source reconstruction. LORETA with a volume-based source space is widely used and much effort has been invested in

Ground State for the Schrödinger Operator with the Weighted Hardy Potential

International Journal of Differential Equations, 2011
We establish the existence of ground states on ℝ𝑁 for the Laplace operator involving the Hardy-type potential. This gives rise to the existence of the principal eigenfunctions for the Laplace operator involving weighted Hardy potentials. We also obtain a

A general quantum Laplace transform

Advances in Difference Equations, 2020
In this paper, we introduce a general quantum Laplace transform L β $\mathcal{L}_{\beta }$ and some of its properties associated with the general quantum difference operator D β f ( t ) = ( f ( β ( t ) ) − f ( t ) ) / ( β ( t ) − t ) ${D}_{\beta }f(t)= ({

Adaptive Discrete Laplace Operator [PDF]

, 2011
Diffusion processes capture information about the geometry of an object such as its curvature, symmetries and particular points. The evolution of the diffusion is governed by the LAPLACE-BELTRAMI operator which presides to the diffusion on the manifold.

Brezis Nirenberg type results for local non-local problems under mixed boundary conditions

Communications in Analysis and Mechanics
In this paper, we are concerned with an elliptic problem with mixed Dirichlet and Neumann boundary conditions that involve a mixed operator (i.e., the combination of classical Laplace operator and fractional Laplace operator) and critical nonlinearity ...
