Abundance for mixed characteristic threefolds
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesMember Seminar Speaker: Iacopo Brivio (CMSA) Title: Abundance for mixed characteristic threefolds Abstract: The Minimal Model Program (MMP) predicts that every algebraic variety X is birational to either a fibration in Fano varieties, or it admits a “minimal model” X', that is a birational model with nef canonical bundle K_X'. The Abundance conjecture predicts then […]
Freedman CMSA Seminar
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesFreedman CMSA Seminar 2:00-3:30 pm ET Speaker: Mike Freedman, Harvard CMSA Title: Detecting hidden structures in linear maps Abstract: I'll consider the problem of detecting spectral features and tensor structures within linear maps both in a quantum and classical contexts. In the quantum context there is the question of whether a Hamiltonian is local, […]
Ringdown in the SYK model
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesJoint BHI/CMSA Foundation Seminar Speaker: Matthew Dodelson (Harvard) Title: Ringdown in the SYK model Abstract: Thermal correlators in large N systems equilibrate at late times, but the precise late-time behavior is unknown away from holographic and free field limits. In this talk I will analyze this problem in the case of the SYK model away from […]

Periodic pencils of flat connections and their p-curvature
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesColloquium Speaker: Pavel Etingof (MIT) Title: Periodic pencils of flat connections and their p-curvature A periodic pencil of flat connections on a smooth algebraic variety is a linear family of flat connections , where are local coordinates on and are matrix-valued regular functions. A pencil is periodic if it is generically invariant under the shifts up to isomorphism. I will […]

Mathematics around Twisted Holography
CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesGeometry and Quantum Theory Seminar Speaker: Keyou Zeng (CMSA) Title: Mathematics around Twisted Holography Abstract: The holography principle is an important idea in physics and has been widely studied since the 90s. Twisted holography offers a way to simplify physical holography models through the procedure called twisting. In the first part of the talk, I’ll […]
