Quantum Cohomology via Vicious and Osculating Walkers
... where λ is any partition in the n × n square. This identity is a true “quantum relation” as it becomes trivial for q = 0, i.e. there exists no analogue of this relation for skew Schur functions where d, d = 0. Similar identities hold also for N ∈ / 2N but look more complicated. They will be stated ...
