Title: The Milne and Kramers Problems for the Boltzmann Equation of a Hard Sphere Gas (2)

Colloquium, 台灣大學數學系 李國瑋教授
Thursday, March 2, 15:10—16:00 數學系3174教室
Title: Constant Mean Curvature Foliation in the Extended Schwarzschild Spacetime
Abstract: In this talk, we first give an introduction to the constant mean curvature (CMC) foliations and the CMC time functions. Then we summarize some CMC foliations results in cosmological spacetimes. For spatially noncompact cases, Schwarzschild spacetimes for example, CMC foliation properties were conjectured by Malec and O Murchadha in [1,2]. These conjectures are completely proved in [3,4,5] and we will show the ideas of these proofs in this talk as well.

Title: Recent Progress on Boltzmann Equation

Colloquium, 中央大學數學系 彭勇寧教授
Thursday, March 16, 15:10—16:00 數學系3174教室
Title: Schur-weyl Duality and Affine Periplectic Brauer Algebras
Abstract: In this talk, we will recall the well-known Schur-Weyl duality and its generalizations that lead us to the discovery of a new algebra b P^-d , called the affine periplectic Brauer algebra. This algebra is defined by generators and relations that are very similar to those of the degenerate affine Nazarov-Wenzl algebra except for some crucial signs. It can be regarded as the (degenerate) affine generalization of the periplectic Brauer algebra introduced by Moon, which can be roughly thought as an algebra dual (in the sense of Schur-Weyl duality) to the periplectic Lie superalgebras. This talk is based on a joint work with Chih-Whi Chen.
