DESCRIPTION:Title: Virtual localization for relative obstruction theories and stable log
maps\nby Tom Graber (Caltech) as part of Stanford algebraic geometry s
eminar\n\n\nAbstract\nI will discuss how to formulate and prove a localiza
tion theorem for the virtual fundamental class of a moduli space with a re
lative perfect obstruction theory over a singular base. In the motivating
example of the moduli space of stable log maps\, I will explain how this
leads to sums over types of tropical curves and cycle classes on moduli sp
aces of curves related to the double ramification cycle that have been of
recent interest in other contexts.\n
