  We interpret the equivariant cohomology algebra
H^*_{GL_n\times\C^*}(T^*F_\lambda;\C) of the cotangent bundle of a partial flag
variety F_\lambda parametrizing chains of subspaces 0=F_0\subset
F_1\subset\dots\subset F_N =\C^n, \dim F_i/F_{i-1}=\lambda_i, as the Yangian
Bethe algebra of the gl_N-weight subspace of a gl_N Yangian module. Under this
identification the dynamical connection of [TV1] turns into the quantum
connection of [BMO] and [MO]. As a result of this identification we describe
the algebra of quantum multiplication on H^*_{GL_n\times\C^*}(T^*F_\lambda;\C)
as the algebra of functions on fibers of a discrete Wronski map. In particular
this gives generators and relations of that algebra. This identification also
gives us hypergeometric solutions of the associated quantum differential
equation. That fact manifests the Landau-Ginzburg mirror symmetry for the
cotangent bundle of the flag variety.
