Title: Scattering Rigidity Problem
General Relativity Seminar Speaker: Jin Jia, Hunan University Title: Scattering Rigidity Problem Abstract: If the asymptotic behavior of a solution to a nonlinear equation is the same as that of a solution to its linearized equation, it is called a scattering solution. Scattering phenomena are widely observed near steady-state solutions of various mathematical physics equations, such as water wave equations, Einstein equations, MHD equations, and Vlasov-Poisson equations. This report takes these equations as examples to provide the definition of scattering operator and its relation to radiation fields. It explains the concepts of scattering rigidity problem and scattering completeness problem, and introduces the latest discoveries of the speaker in the general solution approach to scattering rigidity problem.

Title: Solving olympiad geometry without human demonstrations
New Technologies in Mathematics Seminar Speaker: Trieu H. Trinh, Google Deepmind and NYU Dept. of Computer Science Title: Solving olympiad geometry without human demonstrations Abstract: Proving mathematical theorems at the olympiad level represents a notable milestone in human-level automated reasoning, owing to their reputed difficulty among the world’s best talents in pre-university mathematics. Current machine-learning approaches, however, are not applicable to most mathematical domains owing to the high cost of translating human proofs into machine-verifiable format. The problem is even worse for geometry because of its unique translation challenges, resulting in severe scarcity of training data. We propose AlphaGeometry, a theorem prover for Euclidean plane geometry that sidesteps the need for human demonstrations by synthesizing millions of theorems...

Title: The KSBA moduli space of log Calabi-Yau surfaces
Algebraic Geometry in String Theory Seminar Speaker: Pierrick Emilien Yann Bousseaum, University of Georgia Title: The KSBA moduli space of log Calabi-Yau surfaces Abstract: The KSBA moduli space, introduced by Kollár--Shepherd-Barron, and Alexeev, is a natural generalization of "the moduli space of stable curves" to higher dimensions. It parametrizes stable pairs (X,B), where X is a projective algebraic variety satisfying certain conditions and B is a divisor such that K_X+B is ample. This moduli space is described concretely only in a handful of situations: for instance, if X is a toric variety and B=D+\epsilon C, where D is the toric boundary divisor and C is an ample divisor, it is shown by Alexeev that the KSBA moduli space is...

Title: Decoding The Origins of Fluidity in Multicellular Systems
Active Matter Seminar Speaker: Max Bi (Northeastern University) Title: Decoding The Origins of Fluidity in Multicellular Systems Abstract: Organisms continually adapt to mechanical forces at the cellular and tissue levels, a process crucial for sustaining vital life functions. In pivotal physiological processes, such as cancer progression and embryonic development, tissues are often poised near solid-like and fluid-like states. My talk will delve into three critical aspects of this phenomenon: (1) utilizing computational models that draw parallels with soft matter physics, we examine shear-induced rigidity and the origins of fluidity in epithelial tissues; (2) exploring the intricate relationship between external mechanical stresses and internal cellular dynamics, unraveling a range of rheological behaviors, such as shear thinning and thickening, which...

Title: Non-Invertible Peccei-Quinn Symmetry and the Massless Quark Solution to the Strong CP Problem
Quantum Matter in Mathematics and Physics Seminar Speaker: Sungwoo Hong, Korea Advanced Institute of Science and Technology (KAIST) Title: Non-Invertible Peccei-Quinn Symmetry and the Massless Quark Solution to the Strong CP Problem Abstract: In this talk, I will discuss a new solution to the strong CP problem, one of the most important and challenging problems, of the Standard Model (SM) based on the generalized global symmetry. To this end, I will first show that there exist non-invertible chiral symmetries acting on quark fields once the SM is extended with gauged quark flavor symmetry. Interestingly enough, such symmetries, which we named them as "non-invertible Peccei-Quinn symmetries", exist only because the SM has the same number of generations as colors,...
