SUMMARY:02-03-2017 CMSA Members’ Seminar
DESCRIPTION:Hansol Hong\, Harvard \nTitle: Homological Mirror Functors \nAbstract: I will first give a brief introduction to mirror symmetry\, which intertwines symplectic geometry and complex geometry of a pair of Kahler manifolds\, and explain mirror construction using formal deformation of a Lagrangian submanifold.  We will see that counting of holomorphic discs bounding Lagrangian naturally gives rise to a mirror space (Landau-Ginzburg model) and  a functor from Fukaya category to its mirror matrix factorization category. I will mainly focus on one specific example to give a concrete description of the construction.

SUMMARY:Geometry of 3-manifolds and Complex Chern-Simons Theory
DESCRIPTION:Speaker: Masahito Yamazaki (IMPU) \nTitle: Geometry of 3-manifolds and Complex Chern-Simons Theory \nAbstract: The geometry of 3-manifolds has been a fascinating subject in mathematics. In this talk I discuss a “quantization” of 3-manifold geometry\, in the language of complex Chern-Simons theory. This Chern-Simons theory in turn is related to the physics of 3-dimensional supersymmetric field theories through the so-called 3d/3d correspondence\, whose origin can be traced back to a mysterious theory on the M5-branes. Along the way I will also comment on the connection with a number of related topics\, such as knot theory\, hyperbolic geometry\, quantum dilogarithm and cluster algebras.

SUMMARY:Algebraic Geometry Seminar\, Thursdays
DESCRIPTION:This seminar will not be held in the Spring 2018 Semester. \nThe Algebraic Geometry Seminar will be every Thursday from 3pm-4pm in CMSA Building\, 20 Garden Street\, Room G10. \nThe schedule will be updated as details are confirmed. \n  \n  \n\n\n\nDate\nName\nTitle/Abstract\n\n\n09-14-17\n Yu-Wei Fan (Harvard Math)\n\nEntropy of an autoequivalence on Calami-Yau manifolds \nAbstract:  We will recall the notion of entropy of an autoequivalence on triangulated categories\, and provide counterexamples of a conjecture by Kikuta-Takahashi. \n\n\n\n11-1-17 \n*5:00pm\, G10*\n Shamil Shakirov\, Harvard Math\n\nUndulation invariants of plane curves \nAbstract: “One of the general problems in algebraic geometry is to determine algorithmically whether or not a given geometric object\, defined by explicit polynomial equations (e.g. a curve or a surface)\, satisfies a given property (e.g. has singularities or other distinctive features of interest). A classical example of such a problem\, described by Cayley and Salmon in 1852\, is to determine whether or not a given plane curve of degree r > 3 has undulation points — the points where the tangent line meets the curve with multiplicity four. Cayley proved that there exists an invariant of degree (r – 3)(3 r – 2) that vanishes if and only if the curve has undulation points. We construct this invariant explicitly for quartics (r=4) as the determinant of a 21 times 21 matrix with polynomial entries\, and we conjecture a generalization for r = 5 \n\n\n\n11-2-17 \n \nAlexander Moll\, IHES\n\nHilbert Schemes from Geometric Quantization of Dispersive Periodic Benjamin-Ono Waves \nABSTRACT: By Grojnowski and Nakajima\, Fock spaces are cohomology rings of Hilbert scheme of points in the plane.  On the other hand\, by Pressley-Segal\, Fock spaces are spaces of J-holomorphic functions on the loop space of the real line that appear in geometric quantization with respect to the Kähler structure determined by the Sobolev regularity s= -1/2 and the Hilbert transform J.  First\, we show that the classical periodic Benjamin-Ono equation is a Liouville integrable Hamiltonian system with respect to this Kähler structure.  Second\, we construct an integrable geometric quantization of this system in Fock space following Nazarov-Sklyanin and describe the spectrum explicitly after a non-trivial rewriting of our coefficients of dispersion \ebar = e_1 + e_2 and quantization \hbar = – e_1 e_2 that is invariant under e_2 <-> e_1.  As a corollary of Lehn’s theorem\, our construction gives explicit creation and annihilation operator formulas for multiplication by new explicit universal polynomials in the Chern classes of the tautological bundle in the equivariant cohomology of our Hilbert schemes\, in particular identifying \ebar with the deformation parameter of the Maulik-Okounkov Yangian and \hbar with the handle-gluing element.  Our key ingredient is a simple formula for the Lax operators as elliptic generalized Toeplitz operators on the circle together with the spectral theory of Boutet de Monvel and Guillemin.  As time permits\, we discuss the relation of dispersionless \ebar -> 0 and semi-classical \hbar \rightarrow 0 limits to Nekrasov’s BPS/CFT Correspondence. \n\n\n\n11-9-17\n  TBD\n  TBD\n\n\n11-16-17\n TBD\n TBD\n\n\n11-23-17\n  TBD\n  TBD\n\n\n11-30-17\n  TBD\n  TBD\n\n\n12-7-17\n  TBD\n  TBD\n\n\n12-15-17\n  TBD\n  TBD
