Abstract

Property O, introduced by Galkin et al. for arbitrary complex, Fano manifolds X, is a statement about the eigenvalues of the linear operator obtained by the quantum multiplication by the anticanonical class of X. We prove that property O holds in the case when X = IG(k, 2n + 1) is an odd symplectic Grassmannian. The proof uses the combinatorics of the recently found quantum Chevalley formula for IG(k, 2n + 1), together with the Perron–Frobenius theory of nonnegative matrices.
