Abstract
We determine generators for the codimension 1 Chow
group of the moduli spaces of genus zero stable maps to flag varieties G | P. In the case of SL flags, we find all relations between our
generators, showing that they essentially come from 
. In addition, we
analyze the codimension 2 classes on the moduli spaces of stable maps to
Grassmannians and prove a new codimension 2 relation. This will lead to a
partial reconstruction theorem for the Grassmannian of 2
planes.
