Affine symmetries of the equivariant quantum cohomology ring of rational homogeneous spaces

Pierre-Emmanuel Chaput, Laurent Manivel, Nicolas Perrin

Let $X$ be a rational homogeneous space and let $Q H^{*} (X)_{l oc}^{\times}$ be the group of invertible elements in the small quantum cohomology ring of $X$ localised in the quantum para…

Quantum cohomology of minuscule homogeneous spaces III : semi-simplicity and consequences

Pierre-Emmanuel Chaput, Laurent Manivel, Nicolas Perrin

We prove that the quantum cohomology ring of any minuscule or cominuscule homogeneous space, specialized at q=1, is semisimple. This implies that complex conjugation defines an alg…
