Welcome from the Chair
9th Symmetry Webinar
Different Approaches for the Solutions of Differential Equations
Many important and significant problems in mathematics and in general in applied sciences are formulated through differential equations. In this webinar, we would like to combine an approach to the recent theory on some classes of differential equations, with considerable material and methods of solutions that have proved useful to a wide variety of applications, to methods have a systematic and orderly structure and not merely a miscellaneous collection of unrelated mathematical tricks.
Solving a difficult problem in differential equations often requires the use of a variety of tools, both analytical and numerical: the implementation of an efficient numerical procedure typically rest on a good deal of preliminary analysis, to determine the qualitative features of the solution of the solution as a guide to computation, to test limiting or special cases, and so forth.
Gaining an understanding of a complex natural process is often accomplished by combining or building upon simpler and more basic models.
In this webinar will be presented recent results regarding some relevant differential equations, as the Heun equations, where will review the current state of the theory of these equations, focusing on the expansion of solutions in simpler mathematical functions, primarily of the hypergeometric class and the Grad-Shafranov plasma equilibrium equation, in toroidal geometry, that has been the fundamental step towards the realization of the Tokamak configurations and, consequently on the route towards the achievements of the Fusion energy production, furthermore will be presented adaptive schemes for solving radial basis function collocation problems, which involve elliptic partial differential equations.

University of Tuscia/DTT, Viterbo, Italy
From 1982 up to 2021 I have been working in the ENEA Frascati centrum. Along these years I have worked on several quite different research field, i. e. plasma equilibrium, plasma control, plasma turbulence… I have also spent large part of these years working in the European JET Experiment, leading different groups and as responsible of some enhancements. On the late ENEA period I have been one of the key people on the new Divertor Tokamak Test (DTT) facility proposal, presently under realisation in Frascati. On the 2021 I left ENEA and I became full professor in the Tuscia University.
