Meeting ID: 921 6698 5125 Passcode: 883637

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.

Speaker: Mahir Can, Tulane University 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.

Speaker: Chris Bowman, University of Kent Title: Tautological p-Kazhdan–Lusztig Theory for cyclotomic Hecke algebras Abstract: We discuss a new explicit isomorphism between (truncations of) quiver Hecke algebras and Elias–Williamson’s diagrammatic endomorphism algebras of Bott–Samelson bimodules. This allows us to deduce that the decomposition numbers of these algebras (including as examples the symmetric groups and generalised blob algebras) are tautologically equal to the associated p-Kazhdan–Lusztig polynomials, provided that the characteristic is greater than the Coxeter number. This allows us to give an elementary and explicit proof of the main theorem of Riche–Williamson’s recent monograph and extend their categorical equivalence to cyclotomic Hecke algebras, thus solving Libedinsky–Plaza’s categorical blob conjecture.

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.

I will first describe our recent efforts in deriving a complete statistical solution to the non-hierarchical, chaotic three-body problem. I will then review the status of gravitational wave detections and our current understanding of their origin, and show how three-body interactions play a key role in several formation pathways of gravitational wave events.
