Regularized integrals on Riemann surfaces and correlations functions in 2d chiral CFTs
Abstract: I will report a recent approach of regularizing divergent integrals on configuration spaces of Riemann surfaces, introduced by Si Li and myself in arXiv:2008.07503, with an emphasis on genus […]
What is Mathematical Consciousness Science?
Speaker: Johannes Kleiner, LMU München Title: What is Mathematical Consciousness Science? Abstract: In the last three decades, the problem of consciousness – how and why physical systems such as the brain […]
Late time von Neumann entropy and measurement-induced phase transition
Youtube Video Abstract: Characterizing many-body entanglement is one of the most important problems in quantum physics. We present our studies on the steady state von Neumann entropy and its transition […]
On the wave turbulence theory for a stochastic KdV type equation
Random Matrix & Probability Theory Seminar Speaker: Minh-Binh TRAN (SMU & MIT) Location: CMSA, Room G02 Title: On the wave turbulence theory for a stochastic KdV type equation Abstract: We report recent […]
Gopakumar-Vafa type invariants of holomorphic symplectic 4-folds
Abstract: Gromov-Witten invariants of holomorphic symplectic 4-folds vanish and one can consider the corresponding reduced theory. In this talk, we will explain a definition of Gopakumar-Vafa type invariants for such a reduced […]
Lattice Gauge Theory View of Toric Codes, X-cube, and More
Youtube Video Abstract: Exactly solvable spin models such as toric codes and X-cube model have heightened our understanding of spin liquids and topological matter in two and three dimensions. Their […]
Theories of branching morphogenesis
Abstract: The morphogenesis of branched tissues has been a subject of long-standing debate. Although much is known about the molecular pathways that control cell fate decisions, it remains unclear how […]
The space of vector bundles on spheres: algebra, geometry, topology
Abstract: Bott periodicity relates vector bundles on a topological space X to vector bundles on X “times a sphere”. I’m not a topologist, so I will try to explain an algebraic […]
Synthetic Regression Discontinuity: Estimating Treatment Effects using Machine Learning
Speaker: Jörn Boehnke Title: Synthetic Regression Discontinuity: Estimating Treatment Effects using Machine Learning Abstract: In the standard regression discontinuity setting, treatment assignment is based on whether a unit’s observable score (running […]
Type IIB flux compactifications with $h^{1,1}=0$
Abstract: We revisit type IIB flux compactification that are mirror dual to type IIA on rigid Calabi-Yau manifolds. We find a variety of interesting new solutions, like fully stabilized Minkowski vacua […]
BCFW recursion relations and non-planar positive geometry
Abstract: There is a close connection between the scattering amplitudes in planar N=4 SYM theory and the cells in the positive Grassmannian. In the context of BCFW recursion relations the tree-level […]
