Quantum cohomology via vicious and osculating walkers [PDF]
Christian KorffWe relate the counting of rational curves intersecting Schubert varieties of the Grassmannian to the counting of certain non-intersecting lattice paths on the cylinder. These lattice paths form exactly solvable statistical mechanics or quantum integrable models and are obtained from solutions to the Yang-Baxter equation.View original: http://arxiv.org/abs/1204.4109
