Analytical solutions for time-fractional diffusion equation with heat absorption in spherical domains

open access: yesAin Shams Engineering Journal, 2023
Under the time-variable Dirichlet condition, the time-fractional diffusion equation with heat absorption in a sphere is taken into consideration. The time-fractional derivative with the power-law kernel is used in the generalized Cattaneo constitutive ...

Matrix Inequality for the Laplace Equation

open access: yes, 2017
Since Li and Yau obtained the gradient estimate for the heat equation, related estimates have been extensively studied. With additional curvature assumptions, matrix estimates that generalize such estimates have been discovered for various time-dependent

The jump problem for the laplace equation

open access: yesApplied Mathematics Letters, 2001
The paper is devoted to the jump problem for the Laplace equation outside cuts in a plane. The author studied the problems under considerations with different conditions at infinity, which in turn lead to different uniqueness and existence theorems. Moreover, the singularities of the solutions at the ends of the cuts are investigated.

A comparative study of Bagley–Torvik equation under nonsingular kernel derivatives using Weeks method

open access: yesOpen Physics
Modeling several physical events leads to the Bagley–Torvik equation (BTE). In this study, we have taken into account the BTE, including the Caputo–Fabrizio and Atangana–Baleanu derivatives. It becomes challenging to find the analytical solution to these

Electrovac Universes with a Cosmological Constant

open access: yes, 2014
We present the extension of the Einstein-Maxwell system called electrovac universes by introducing a cosmological constant $\Lambda$. In the absence of the $\Lambda$ term, the crucial equation in solving the Einstein-Maxwell system is the Laplace ...
