  • Abstract: The Gromov norm is a way of assigning a numerical invariant to a cohomology class. One of its important applications is that it gives a-priori bounds on characteristic numbers such as the simplicial volume and the Toledo invariant. However, to this day it has only been calculated for very few cohomology classes. I will discuss new computations of the Gromov norm for degree 4 classes of Hermitian symmetric spaces. Joint work with Caterina Campagnolo and Tobias Hartnick.
