A Truncated-Kernel Mollification Method for the Cauchy Problem of the Modified Helmholtz Equation

Axioms
This paper addresses the Cauchy problem for the multi-dimensional modified Helmholtz equation, a classical and severely ill-posed problem. A truncated-kernel mollification method is proposed as an effective regularization approach.

A General Mollification Regularization Method to Solve a Cauchy Problem for the Multi-Dimensional Modified Helmholtz Equation

Symmetry
This paper considers a Cauchy problem for the multi-dimensional modified Helmholtz equation with inhomogeneous Dirichlet and Neumann data. The Cauchy problem is severely ill-posed, and a general mollification method is introduced to solve the problem. Both the a priori and a posteriori choice strategies of the regularization parameter are proposed, and

A Regularization Method to Solve a Cauchy Problem for the Two-Dimensional Modified Helmholtz Equation

Mathematics, 2019
In this paper, the ill-posed problem of the two-dimensional modified Helmholtz equation is investigated in a strip domain. For obtaining a stable numerical approximation solution, a mollification regularization method with the de la Vallée Poussin ...

A Mollification Regularization Method for a Fractional-Diffusion Inverse Heat Conduction Problem [PDF]

Mathematical Problems in Engineering, 2013
The ill-posed problem of attempting to recover the temperature functions from one measured transient data temperature at some interior point of a one-dimensional semi-infinite conductor when the governing linear diffusion equation is of fractional type is discussed.

The Advantage of Regularizing a Specific Elliptical Problem by the Truncation and Mollification Methods

, 2023
The try to prove the importance and advantage of using the truncation method and the mollification method to regularize an ill-posed elliptical problem. To find appropriate solutions, we will try to calculate the difference between the original solution and the approximate solution. We give a concrete example to see how to apply the theoretical results

A regularized version of the Kuwabara-Kono force scheme for 2nd order convergence in DEM simulations of granular materials [PDF]

EPJ Web of Conferences
The Discrete Element Method is a technique widely used to simulate multi-particle systems, in particular granular materials. For conservative systems, the integration of the equations of motion is often performed via a Verlet-type method of order two ...
