Quantum algebras and R-matrices from the equivariant affine Grassmannians
VirtualMathematical Physics and Algebraic Geometry Seminar Speaker: Wenjun Niu, Perimeter Institute Title: Quantum algebras and R-matrices from the equivariant affine Grassmannians Abstract: In this talk, I will explain my joint work with R. Abedin, in which we construct, for each Lie algebra g, a Hopf algebra and a spectral R-matrix satisfying quantum Yang-Baxter equation. This […]
Is every knot isotopic to the unknot?
VirtualFreedman CMSA Seminar *via Zoom* Speaker: Sergey Melikhov, Steklov Math Institute Title: Is every knot isotopic to the unknot? Abstract: The following problem was stated by D. Rolfsen in his 1974 paper; according to R. Daverman it was being discussed since the mid-60s. Is every knot in $S^3$ isotopic (=homotopic through embeddings) to a PL knot --- […]
Joint BHI/CMSA Foundation Seminar: Quantum Effects Inside Black Holes
Black Hole Initiative, 20 Garden Street, Cambridge MA CMSA, 20 Garden Street, Cambridge, MA, United StatesJoint BHI/CMSA Foundation Seminar Location: BHI seminar room Speaker: Noa Zilberman (Princeton University) Title: Quantum Effects Inside Black Holes Abstract: Astrophysical black holes are known to be rotating. Within classical General Relativity, the simplest spacetime solution (the Kerr solution) describing a rotating black hole reveals a traversable passage through an inner horizon – which in […]
On 5d conformal matter
VirtualQuantum Field Theory and Physical Mathematics Seminar Speaker: Mario De Marco (UL Brussels) Title: On 5d conformal matter Abstract: SCFTs with 8 supercharges lie at the sweet spot of the classification program of susy scale-invariant theories: with this amount of susy, the classification is in principle achievable, despite being non-trivial. In this talk, I will present […]

AI in math and theoretical physics: Status and prospects
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesColloquium Speaker: Michael Douglas, Harvard CMSA Title: AI in math and theoretical physics: status and prospects Abstract: AI is making great progress and has the potential to change how we work in unprecedented ways. In this talk I will survey a few recent works which illustrate the state of the art, some from my own research, […]
On the past maximal development of near-FLRW data for the Einstein scalar-field Vlasov system
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesGeneral Relativity Seminar Speaker: Liam Urban (University of Vienna) Title: On the past maximal development of near-FLRW data for the Einstein scalar-field Vlasov system Abstract: In recent years, the formation of Big Bang singularities has been increasingly well understood in presence of scalar-field matter, which suppresses the geometric oscillations that one generically expects otherwise. From a cosmological perspective, […]

CMSA Q&A Seminar: Javier Gomez-Serrano
Common Room, CMSA 20 Garden Street, Cambridge, MA, United StatesCMSA Q&A Seminar Speaker: Javier Gomez-Serrano, Brown University Topic: Please tell us about the Millennium prize problem for Navier-Stokes and segue from that into ML?
Discovering Data Structures: Nearest Neighbor Search and Beyond
Virtualhttps://youtu.be/_BgheUBw_Lw New Technologies in Mathematics Seminar Speaker: Omar Salemohamed, Mila Title: Discovering Data Structures: Nearest Neighbor Search and Beyond Abstract: As neural networks learn increasingly sophisticated tasks—from image recognition to mastering the game of Go—we ask: can deep learning discover data structures entirely from scratch? We introduce a general framework for data structure discovery, which adapts to […]
The Structure of the Flux Landscape
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesMathematical Physics and Algebraic Geometry Seminar Speaker: Damian Van de Heisteeg, Harvard CMSA Title: The Structure of the Flux Landscape Abstract: Identifying flux vacua in string theory with stabilized complex structure moduli presents a significant challenge, necessitating the minimization of a scalar potential complicated by infinitely many exponential corrections. In order to obtain exact results we […]
