Convolutions with probability densities and applications to PDEs
Electronic Journal of Differential Equations, 2017 In this article we introduce several new convolution operators, generated by some known probability densities. By using the inverse Fourier transform and taking inverse steps (in the analogues of the classical procedures used for example in the heat ...

A Singular Initial-Value Problem for Second-Order Differential Equations
Abstract and Applied Analysis, 2014 We are interested in the existence of solutions to initial-value problems for second-order nonlinear singular differential equations. We show that the existence of a solution can be explained in terms of a more simple initial-value problem.
