The recipients were chosen by the UConn-AAUP Excellence Awards Committee from a pool of excellent candidates. The recognition of faculty teaching, research, and service excellence through UConn-AAUP awards began in 1997. The [ ][Read More] In 1993, Morrison conjectured that the automorphism group of a Calabi-Yau 3-fold acts on its nef cone with a rational polyhedral fundamental domain. In this talk, I will discuss a version of this conjecture for log Calabi-Yau surfaces that we have proved. In particular, for a generic log Calabi-Yau surface with singular boundary, the monodromy group acts on the nef effective cone with a rational polyhedral fundamental domain. In addition, the automorphism group of the unique surface with a split mixed Hodge structure in each deformation type acts on the nef effective cone with a rational polyhedral fundamental domain.Please contact the organizer for the WebEx link. Speaker: Wei-Kuo Chen(University of Minnesota)Title: Grothendeick L_p problem for Guaussian matricesAbstract:The Grothendieck L_p problem is defined as an optimization problem that maximizes the quadratic form of a Gaussian matrix over the unit L_p ball. The p=2 case corresponds to the top eigenvalue of the Gaussian Orthogonal Ensemble, while p=\infty this problem is known as the ground state energy of the Sherrington-Kirkpatrick mean-field spin glass model and its limit can be expressed by the famous Parisi formula. In this talk, I will describe the limit of this optimization problem for general p and discuss some results on the behavior of the near optimizers along with some open problems. This is based on a joint work with Arnab Sen. The Department of Mathematics' Annual Awards Day Ceremony to celebrate our student's achievements. Join us for this week's Logic Colloquium!Bjørn Jespersen (Utrecht)"Impossibilities without impossibilia"Circumstantialists already have a logical semantics for impossibilities. They expand their logical space of possible worlds by adding impossible worlds. These are impossible circumstances serving as indices of evaluation, at which impossibilities are true. A variant of circumstantialism, namely modal Meinongianism, adds impossible objects as well. The opposite of circumstantialism, namely structuralism, has some catching-up to do. What might a structuralist logical semantics without impossible worlds or impossible objects look like? This paper makes a structuralist counterproposal. I present a semantics based on a procedural interpretation of the typed l-calculus. The fundamental idea is that talk about impossibilities should be construed in terms of procedures yielding as their product a condition that could not possibly have a satisfier, or else failing to yield a product at all. Dispensing with a ‘bottom’ of impossibilia requires instead a ‘top’ consisting of structured hyperintensions, intensions, intensions defining other intensions, a typed universe, and dual predication. I explain how the theory works by going through a couple of cases. Zoom We define and study the windings along Brownian paths in the octonionic Euclidean, projective and hyperbolic spaces which are isometric to 8-dimensional Riemannian model spaces. In particular, as the applications of the Girsanov theorem and the polar decomposition of the Brownian motion on Riemannian manifolds, the asymptotic laws of these windings are shown to be Gaussian for the flat and spherical geometries, while the hyperbolic winding exhibits a different long time behavior. This is a joint work with Guang Yang. The necessary background including Riemannian and sub-Riemannian geometry would be reviewed to follow this talk.
