Title: A Tetrahedral Approach to Calabi-Yau Geometry

Member Seminar Speaker: Charles Doran, CMSA Title: A Tetrahedral Approach to Calabi-Yau Geometry Abstract:  We will open with a quick introduction to the what and why of Calabi-Yau geometry.  Following this, we will consider the problem of deforming tetrahedra while preserving the areas of their faces, following our noses to discover a beautiful path to elliptic curves, K3 surfaces, and beyond.  Time permitting, we will also discuss motivations and applications across physics.  The talk should be broadly accessible.  

Title: Comments on Non-Invertible Symmetries in K3 CFTs and the Conway Moonshine Module

Quantum Field Theory and Physical Mathematics Seminar Speaker: Sarah Harrison, Northeastern Title: Comments on Non-Invertible Symmetries in K3 CFTs and the Conway Moonshine Module Abstract: There is an established connection between discrete symmetry groups of K3 non-linear sigma models and a distinguished N=1 chiral SCFT called the Conway moonshine module. More specifically, all symmetry groups of K3 NLSMs preserving the N=4 superconformal algebra can be obtained as subgroups of "Conway zero", the group of symmetries of the Conway module, and their explicit action on the BPS spectrum can (almost always) be obtained via traces in the Conway module. A natural question is whether this relation extends to fusion category symmetry of these theories. I will discuss positive evidence...

Title: Positive scalar curvature with point singularities

General Relativity Seminar Speaker: Rudolf Zeidler, Mathematical Institute, University of Münster Title: Positive scalar curvature with point singularities Abstract: I will explain a certain topological construction of positive scalar curvature metrics with uniformly Euclidean ($L^\infty$) point singularities. This provides counterexamples to a conjecture of Schoen. It also shows that there are metrics with uniformly Euclidean point singularities which cannot be smoothed via a geometric flow while simultaneously preserving non-negativity of the scalar curvature. Based on recent joint work with Simone Cecchini and Georg Frenck.

Title: Discovery in Mathematics with Automated Conjecturing

New Technologies in Mathematics Seminar Speaker: Randy Davila, RelationalAI and Rice University Title: Discovery in Mathematics with Automated Conjecturing Abstract: Automated conjecturing is a form of artificial intelligence that applies heuristic-driven methods to mathematical discovery. Since the late 1980s, systems such as Fajtlowicz’s Graffiti, DeLaViña’s Graffiti.pc, and TxGraffiti have collectively contributed to over 130 publications in mathematical journals. In this talk, we outline the evolution of automated conjecturing, focusing on TxGraffiti, a program that employs linear optimization methods and several distinct heuristics to generate mathematically meaningful conjectures. We will then introduce GraphMind, a dueling framework where the Optimist proposes conjectures while the Pessimist seeks counterexamples, fostering a feedback loop that strengthens automated reasoning. Finally, we will present GraffitiAI, a Python...
