WEEKLY  CALENDAR
March 2008
Vanderbilt Mathematics


Monday 10
 3:10-4:00 pm, room 1432. Subfactor Seminar. Alan Wiggins, Vanderbilt University. A new construction of subfactors from random matrix theory V.
Tuesday 11
 4:10-5:15 pm, room 1431. Noncommutative Geometry Seminar. Yves de Cornulier, IRMAR, Univ. of Rennes I. Haagerup property for wreath products. We prove (joint with Stalder and Valette) that the class of groups with the Haagerup Property is closed under wreath products. The proof relies on the characterization of the Haagerup property by actions on spaces with measured walls.
4:10-5:30 pm, room 1432. Universal Algebra and Logic Seminar. Rostislav Horcik, Czech Republic Academy of Sciences, Prague. Applications of non-formally-integral totally ordered monoids in non-classical logics. AND Peter Cintula, Czech Republic Academy of Sciences, Prague. Hierarchies of implications and disjunctions in non-classical logics.
7-8 pm, room 1206. Undergraduate Seminar in Mathematics. Abey Lopez, Vanderbilt University. Number Theory. Free pizza.

Thursday 13
 4:10-5 pm, room 5211. Colloquium. Serguei P. Novikov, University of Maryland and Landau Institute. New discretization of complex analysis. A new discretization of complex analysis and geometric GL_n connections was found (in collaboration with I. Dynnikov) a few years ago as a by-product of the theory of integrable systems. We are using an equilateral triangle lattice instead of the standard square lattice for complex analysis, and simplicial complexes for GL_n connections. Tea at 3:30 pm in SC 1425.
Friday 14
 4:10-5:00 pm, room 1307. Partial Differential Equations Seminar. Jan Prüss, Martin-Luther Universität Halle-Wittenberg, Germany. Qualitative behavior of solutions for the generalized Stefan problem with surface tension. Strong local well-posedness for the generalized two-phase Stefan problem with surface tension and with or without kinetic undercooling is discussed. The only equilibria of this system are constant temperatures and finitely many non-intersecting spheres with equal radii. The stability of such equilbria is discussed by means of the generalized principle of linearized stability. We show that a solution which does not exhibit singularities is global and converges to one of these equilibria as time tends to infinity.

In the online version of this page, all underlined phrases are links; some mathematical symbols may require a browser with symbol font. Past calendars are available, as well as next week's calendar (in preparation) and a web page listing just our colloquia. We update the online calendar whenever we get information, but generally we only print paper copies on Fridays. Please submit events as early as possible, to math.calendar@vanderbilt.edu.
