Solution of partial differential equations by new double integral transform (Laplace - Sumudu transform)

open access: yesAin Shams Engineering Journal, 2021
The primary purpose of this research is to demonstrate an efficient new double transform mentioned since the double Laplace - Sumudu transform (DLST) solve partial differential equations. The theorems handling fashionable properties of the double Laplace

Tutte's invariant approach for Brownian motion reflected in the quadrant [PDF]

open access: yes, 2016
We consider a Brownian motion with drift in the quarter plane with orthogonal reflection on the axes. The Laplace transform of its stationary distribution satisfies a functional equation, which is reminiscent from equations arising in the enumeration of (

Irregular holonomic kernels and Laplace transform [PDF]

open access: yes, 2014
Given a (not necessarily regular) holonomic D-module defined on the product of two complex manifolds, we prove that the associated correspondence commutes (in some sense) with the De Rham functor.

The kernel of the generalized Clifford-Fourier transform and its generating function [PDF]

open access: yes, 2016
In this paper, we study the generalized Clifford-Fourier transform using the Laplace transform technique. We give explicit expressions in the even dimensional case, we obtain polynomial bounds for the kernel functions and establish a generating ...

Laplace - Fibonacci transform by the solution of second order generalized difference equation

open access: yesNonautonomous Dynamical Systems, 2017
The main objective of this paper is finding new types of discrete transforms with tuning factor t. This is not only analogy to the continuous Laplace transform but gives discrete Laplace-Fibonacci transform (LFt). This type of Laplace-Fibonacci transform

Transparent boundary conditions based on the Pole Condition for time-dependent, two-dimensional problems [PDF]

open access: yes, 2012
The pole condition approach for deriving transparent boundary conditions is extended to the time-dependent, two-dimensional case. Non-physical modes of the solution are identified by the position of poles of the solution's spatial Laplace transform in ...

Laplace transform ordering of bivariate inactivity times

open access: yesAIMS Mathematics, 2022
In this paper we consider the Laplace transform of the bivariate inactivity time. We show that a weak bivariate reversed hazard rate order is characterized by the Laplace transform of the bivariate inactivity times in two different frames.
