Title: Spherical Varieties and Combinatorics
Abstract: Let G be a reductive complex algebraic group with a Borel subgroup B. A spherical G-variety is an irreducible normal G-variety X where B has an open orbit. If X is affine, or if it is projective but endowed with a G-linearized ample line bundle, then the group action criteria for the sphericality is in fact equivalent to the representation theoretic statement that a certain space of functions (related to X) is multiplicity-free as a G-module. In this talk, we will discuss the following question about a class of spherical varieties: if X is a Schubert variety for G, then when do we know that X is a spherical L-variety, where L is the stabilizer of X in G.

Title: The three-body problem from Newton to gravitational waves
Speaker: Dr. Alessandro Alberto Trani
Abstract:
The gravitational few-body problem is one of the oldest conundrums in astronomy and classical mechanics. Yet, its simplest instance, the three-body problem, has no general analytical solution and only a partial statistical solution has been achieved so far. With the birth of gravitational wave astronomy and the rise in exoplanet discoveries, the three-body problem is again becoming central to explaining astrophysical phenomena.

Recent discussions in neuroscience have been arguing about the necessity of a revision to our approach in neuroscience. A common approach in neuroscience starts from a phenomenon such as attention or memory as defined from our psychological heritage, trying to find a brain correlate of this phenomenon. This method has been argued to be suffering from two main problems first is the loosely defined psychological terms and second is the correlation fallacy that has been a major concern in neuroscience. We invited two experts in neuroscience from both OIST and RIKEN trying to get their insight on this problem and how different experimental, mathematical and analytical techniques will help us frame a new path in neuroscience research.
