Discrete stability analysis of the mollification method for numerical differentiation
Computers & Mathematics with Applications, 1990 A numerical differentiation procedure is proposed based on discrete mollification. Numerical stability is proved and error analysis of the numerical procedure is presented. An example is considered of a function identification problem in transient heat conduction.

Mollification of Fourier Spectral Methods with Polynomial Kernels [PDF]
Mathematical Methods in the Applied Sciences, 2023 Many attempts have been made in the past to regain the spectral accuracy of the spectral methods, which is lost drastically due to the presence of discontinuity. In this article, an attempt has been made to show that mollification using Legendre and Chebyshev polynomial based kernels improves the convergence rate of the Fourier spectral method ...

, 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 proposed methodology for mollification of subsynchronous oscillation in DFIG-based wind farm. [PDF]
Sci RepHigh levels of series compensation in transmission lines, particularly those integrated with wind farms, exacerbate the risk of sub-synchronous oscillation (SSO), a phenomenon detrimental to system stability.

A mollification regularization method for the Cauchy problem of an elliptic equation in a multi-dimensional case [PDF]
Inverse Problems in Science and Engineering, 2010 In this article, we consider a Cauchy problem of an elliptic equation in a multi-dimensional case. This problem is severely ill-posed: the solution (if it exists) does not depend continuously on the data. To deal with this problem, we propose a mollification method.

Solution of inverse heat conduction problems with phase changes by the mollification method
Computers & Mathematics with Applications, 1992 Gewisse freie Randwertprobleme (etwa Schmelzprobleme) lassen sich umformulieren in inverse Wärmeleitprobleme, die allerdings ``ill- posed'' sind. Die vorliegende Arbeit befaßt sich mit der numerischen Behandlung solcher Probleme: Ausgehend von einem Glättungsverfahren wird ein explizites und unbedingt stabiles Differenzenverfahren verwendet, mit dem in

Computers & Mathematics with Applications, 1989 The inverse heat conduction problem is mathematically improperly posed in the sense that the solution does not depend continuously upon the data. In order to cope with this difficulty, many methods have been proposed (they are mentioned in the introduction), and in the present paper, the author suggests another one.
