The moment graph for Bott-Samelson varieties and applications to quantum cohomology
We give a description of the moment graph for Bott-Samelson varieties in arbitrary Lie type. We use this, along with curve neighborhoods and explicit moduli space computations, to compute a presentation for the small quantum cohomology ring of a particular Bott-Samelson variety in Type A.

… be the associated affine Weyl group. The moment graph for X encodes the torus fixed points (which are elements of the affine Weyl group W<sub>aff</sub> and the torus stable curves in X. Given a fixed point u ∈ W<sub>aff</sub> and a degree d = (d₀, d₁, ..., d<sub>n−1</sub>) ∈ …
