DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TGiZ/35/">Cu
 t-and-paste invariants of moduli spaces of relative stable maps to $\\math
 bb{P}^1$</a>\nby Siddharth Kannan (Brown University) as part of Tropical G
 eometry in Frankfurt/Zoom TGiF/Z\n\n\nAbstract\nI will discuss ongoing wor
 k studying moduli spaces of genus zero stable maps to $\\mathbb{P}^1$\, wi
 th fixed ramification profiles over $0$ and infinity. I will describe a ch
 amber decomposition of the space of ramification data such that the Grothe
 ndieck class of the moduli space is constant on the chambers. Finally\, fo
 r the sequence of ramification data corresponding to maximal ramification 
 over $0$ and no ramification over infinity\, I will describe a recursive a
 lgorithm to compute the generating function for Euler characteristics of t
 hese spaces.\n
