DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BUGeom/21/">
 Tropical multiplicities from polyvector fields and QFT</a>\nby Travis Mand
 el (University of Oklahoma) as part of Boston University Geometry/Physics 
 Seminar\n\nLecture held in Zoom meeting ID: 974 5641 9902.\n\nAbstract\nWh
 en considering planar tropical curves satisfying point conditions\, Mikhal
 kin expressed the tropical curves' multiplicities as the product of the mu
 ltiplicities of their vertices.  Such a decomposition of the multiplicity 
 into local computations is very useful in practice\, e.g.\, in the Gross-S
 iebert program.  I will describe joint work with H. Ruddat in which we giv
 e such localized tropical multiplicity formulas very generally (in genus 0
 ) using mirror polyvector fields.  Our approach involves developing a noti
 on of tropical quantum field theory which works for all genera.\n
