Abstract: Conifold transitions are important algebraic geometric constructions that have been of special interests in mirror symmetry, transforming Calabi-Yau 3-folds between A- and B-models. In this talk, I will discuss […]
Title: Cornering the universal shape of fluctuations and entanglement Abstract: Understanding the fluctuations of observables is one of the main goals in physics. We investigate such fluctuations when a subregion […]
https://youtu.be/leONsS4LiV4 Speaker: JM Landsberg, Texas A&M Title: The complexity of matrix multiplication approached via algebraic geometry and representation theory Abstract: In 1968 V. Strassen discovered the way we usually multiply […]
Title: Quantum gravity from quantum matter Abstract: We present a model of quantum gravity in which dimension, topology and geometry of spacetime are collective dynamical variables that describe the pattern […]
Title: Asymptotic localization, massive fields, and gravitational singularities Abstract: I will review three recent developments on Einstein’s field equations under low decay or low regularity conditions. First, the Seed-to-Solution Method […]
Member Seminar Speaker: Michael Simkin Title: Threshold phenomena in random graphs and hypergraphs Abstract: In 1959 Paul Erdos and Alfred Renyi introduced a model of random graphs that is the cornerstone […]
Title: More Exact Results in Gauge Theories: Confinement and Chiral Symmetry Breaking Abstract: In this follow-up to Hitoshi Murayama’s talk “Some Exact Results in QCD-like and Chiral Gauge Theories”, I […]
Abstract: One can view a partial flag variety in C^n as an adjoint orbit inside the Lie algebra of n x n skew-Hermitian matrices. We use the orbit context to […]
During the 2021–2022 academic year, the CMSA will host a program on the so-called “Swampland.” The Swampland program aims to determine which low-energy effective field theories are consistent with nonperturbative quantum gravity considerations. Not […]
Speaker: John Stout, Harvard University Title: Decoding Divergent Distances Abstract: Motivated by a relationship between the Zamolodchikov and NLSM metrics to the so-called quantum information metric, I will discuss recent work […]
Abstract: Calabi–Yau manifolds of a given dimension are connected by an intricate web of birational maps. This web has deep consequences for the derived categories of coherent sheaves on such manifolds, […]
Speaker: Tian Yang (Texas A&M University) Title: Hyperbolic Geometry and Quantum Invariants Abstract: There are two very different approaches to 3-dimensional topology, the hyperbolic geometry following the work of Thurston and the quantum invariants […]
