ODELJENJE ZA MATEMATIKU
MATEMATICKOG INSTITUTA SANU
Sastanci se odrzavaju petkom u 11 casova
(OBRATITE PAZNJU NA PROMENU TERMINA).
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.
