ODELJENJE ZA MATEMATIKU

MATEMATICKOG INSTITUTA SANU

Sastanci Odeljenja za Matematiku odrzavaju se u biblioteci Matematickog Instituta SANU, Kneza Mihaila 35, Beograd, na prvom spratu.

Sastanci se odrzavaju petkom u 11 casova

Molimo da obratite paznju na PROMENU TERMINA. Ubuduce ce sastanci Odeljenja stalno pocinjati u
11 casova (umesto u 12 casova)
kako bi se izbeglo preklapanje sa sednicama na Matematickom fakultetu i omogucilo svima koji zele da prisustvuju obema sednicama.

ODELJENJE ZA MATEMATIKU je opsti seminar sa najduzom tradicijom u Institutu. Predavanja su namenjena sirokom krugu matematicara - i onima koji ne rade u toj oblasti. POSEBNO SU DOBRODOSLI POSTDIPLOMCI I STUDENTI STARIJIH GODINA.

Methods based on Fourier series in hydromagnetic stability theory

Abstract: In linear stability of fluid flows and equilibria subject to several effects (e.g. temperature, concentration, magnetic field) the governing ordinary differential equations are of high order (usually more than 10) and contain several (usually more than three) parameters. In addition, the equations are not selfadjoint and the corresponding eigenvalues are not simple. Finally, the boundary conditions are quite complicate. As a consequence the Fourier series expansion methods of Galerkin type based on total sets of expansion functions satisfaying all boundary conditions are no longer appropriate. This is why we used Budiansky-DiPrima method in which the expansion functions do not satisfy all boundary conditions, thus introducing some constraints. We reveal the main steps in its application to magnetic convections. We also show the advantages and the peculiarities of this method if applied to the associated variational setting.
