Abstract

We propose a notion of Frobenius-Perron dimension for certain free Z\mathbb{Z}-modules of infinite rank and compute it for the Z\mathbb{Z}-modules of finite dimensional complex representations of unitary groups with nonnegative dominant weights. We also provide a lower bound for the Frobenius-Perron dimension of Schubert classes in the quantum cohomology of complex Grassmannians.
