  In this paper we use three-dimensional gauged linear sigma models to make
physical predictions for Whitney-type presentations of equivariant quantum K
theory rings of partial flag manifolds, as quantum products of universal
subbundles and various ratios, extending previous work for Grassmannians.
Physically, these arise as OPEs of Wilson lines for certain Chern-Simons
levels. We also include a simplified method for computing Chern-Simons levels
pertinent to standard quantum K theory.
