HOMOTOPY DECOMPOSITIONS OF GAUGE GROUPS WITH APPLICATIONS TO MODULI SPACES

Abstract: We focus on gauge groups of principal U(n)-bundles over compact Riemann surfaces. In many cases the gauge groups are decomposed, up to homotopy equivalence, as products of other more well known spaces. As a consequence, the calculation of their homotopy groups reduces to that of spheres or U(n). This can then be applied to calculate the homotopy groups of certain moduli spaces through a range, answering a question of Daskalopolous and Uhlenbeck.

ON WEIGHTED STOLARSKY MEANS

Abstract: The class of Stolarsky means is one of most interesting and most investigated family of two-parametric means. In this talk we introduce a weighted variant of Stolarsky means and derive some common properties of those classes of means. An advantage of this concept is the possibility of an extension to the multi-variable case in a simple and applicable way. Some basic inequalities concerning this matter are also established with applications in Analysis and Probability Theory.

HARMONIJSKA KVAZIKONFORMNA PRESLIKAVANjA

Sadrzaj: Razmatramo granicno ponasanje takvih preslikavanja, u proizvoljnoj dimenziji, posebno procene izvoda (tangencijalnih i netangencijalnih), pripadnost Helderovim klasama do na granicu, kao i klasama definisanih opstim modulima neprekidnosti. Takodje ce se razmatrati i ponasanje nekih prirodnih metrika pri takvim preslikavanjima.

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).
