Na UP IAM in UP Famnit smo 19. februarja 2015 gostili uglednega profesorja dr. Franca Brezzija, visokocitiranega raziskovalca (ISI Highly Cited Researcher) z "Istituto Universitario di Studi Superiori (IUSS)" v Pavii, člana evropske akademije znanosti in podpredsednika evropskega matematičnega združenja European Mathematical Society.

Profesor je izvedel predavanje za študente UP, nato se je srečal z dekanjo UP Famnit in direktorjem UP IAM. Pogovorili so se o možnih raziskovalnih sodelovanjih na področju numerike. Nato sta dekanja in direktor dr. Brezzija ter njegovo ženo, prav tako ugledno raziskovalko s področja numerike, dr. Donatello Marini, spremila na sprejem pri rektorju UP, dr. Draganu Marušiču.

Povzetek predavanja, ki ga je profesor dr. Franco Brezzi, izvedel študentom UP: The Virtual Element method is a very recent variant of Finite Element Methods, appeared on the scene a couple of years ago. The method could be seen as a combination of Finite Element Methods and Mimetic Finite Differences. In particular it allows, at the same time, the use of very general decompositions of the computational domain (in almost arbitrary polygons or polyhedra), and the use of the (more elegant and more clarifying) Galerkin framework for the analysis and the error estimates. The talk, addressed to a rather general audience of mathematicians, will describe first the general idea of the method on a very simple problem like Poisson problem in 2 dimensions, and then give some very quick hints on various generalizations, including 3D problems, Stokes problem, Kirchhoff plates, variable coefficients, mixed formulations, etc. Much more details could be given, after the lecture, to the interested people. Several papers (both on the basic principles and on further extensions) can be found (and downloaded) on the web page of the speaker: http://www.imati.cnr.it/brezzi/rec_pubbl.html (the newest are at the end).
