| Résume | I will interpret the equivariant cohomology of the cotangent bundle of a flag variety F as the XXX Bethe algebra of a suitable Yangian module. Under this identification the dynamical connection of the XXX model turns into the quantum connection of Braverman-Maulik-Okounkov.
This gives a relation between the quantum integrable chain models and quantum cohomology algebras, the relation discussed in physics literature by Nekrasov and Shatashvili. |
