DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TGiZ/67/">Mo
 duli spaces of twisted maps to smooth pairs</a>\nby Robert Crumplin (Unive
 rsität Heidelberg) as part of Tropical Geometry in Frankfurt/Zoom TGiF/Z\
 n\n\nAbstract\nThe question of counting maps from marked curves with fixed
  tangency conditions to a divisor in the target has been studied extensive
 ly over the past 15 years. One way of formulating these enumerative proble
 ms is via twisted maps to a root stack. I will describe the geometry of mo
 duli spaces of twisted maps using tropical techniques\, in particular givi
 ng new understanding to universal structural results of orbifold Gromov–
 Witten invariants. If time permits\, I will talk about upcoming work with 
 Sam Johnston which relates these moduli spaces to their logarithmic counte
 rparts and provides a splitting of the virtual class in terms of the afore
 mentioned tropical data.\n
