Cetvrtak, 27. septembar 2007. u 17h, sala 2 MI SANU:

V.A. Kondratiev, Moscow State University
STATIONARY SOLUTIONS, BLOW UP OF SEMILINEAR PARABOLIC EQUATIONS WITH NONLINEAR BOUNDARY CONDITIONS

I. Gutman, D. Cvetkovic, D. Stevanovic
ENERGIJA GRAFA

Energija grafa je zbir modula sopstvenih vrednosti (matrice susedstva) grafa. Ovu grafovsku invarijantu je uveo 1978. godine Ivan Gutman, motivisan nekim problemima kvantne hemije, ali su problemi proucavanja ove invarijante pobudili veliku paznju matematicara, narocito poslednjih godina. To se ogleda i u cinjenici da su proteklih meseci tri clana projekta BR. 144015G, "TEORIJA GRAFOVA I MATEMATICKO PROGRAMIRANJE SA PRIMENAMA U HEMIJI I TEHNICKIM NAUKAMA", pozvani na tri konferencije da odrze plenarna predavanja o energiji grafa:

1. I. Gutman, Workshop on Algebraic Graph Theory, April 2007, Teheran, Iran;

2. D. Cvetkovic, 6th Slovenian International Conference on Graph Theory 24-30 June 2007, Bled, Slovenia;

3. D.Stevanovic, Workshop on Spectra of families of matrices described by graphs, digraphs, and sign patterns, October 23 to October 27, 2006, American Institute of Mathematics, Palo Alto, California.

Trojica predavaca ce u nesto kondenzovanom obliku reprodukovati svoja predavanja o energiji grafa sa navedenih naucnih skupova.

Petak, 28. septembar 2007. u 14h, sala 2, SANU, BG:

Michael Ruzhansky, Mathematics Department, Imperial College London
Regularity properties of Fourier integrals and hyperbolic equations

Abstract: In this talk we will give a survey of the regularity theory of pseudo-differential operators and of Fourier integral operators, with applications to hyperbolic partial differential equations. We will discuss local and global properties, as well as properties in Colombeau's spaces.

There are several interesting connections between properties of these operators in Sobolev spaces with some open questions in symplectic and analytic geometries. In particular, we will present some related open problems that can be formulated entirely in terms of the complex analytic geometry.


Rukovodioci Odeljenja za matematiku Matematickog instituta SANU i Opsteg matematickog seminara na Matematickom fakultetu u Beogradu, Stevan Pilipovic i Sinisa Vrecica predlazu zajednicki program rada naucnih sastanaka.

Predavanja ce se odrzavati na Matematickom Institutu (sala 2), petkom sa pocetkom u 14 casova. Odeljenje za matematiku je opsti seminar sa najduzom tradicijom u Institutu.

Svakog meseca, jedno predavanje ce biti odrzano na Matematickom Fakultetu u terminu koji ce biti posebno odredjen.

Molimo sve zainteresovane ucesnike u radu naucnih sastanaka da posebno obrate paznju na vreme odrzavanja svakog sastanka. Na Matematickom fakultetu su moguce izmene termina.

Obavestenje o programu naucnih sastanaka ce biti objavljeno na oglasnim tablama MI (Beograd), MF (Beograd), PMF (Novi Sad), PMF (Nis) i PMF (Kragujevac).
