Chern character of Schur bundles

Alessandro D'Andrea, Enrico Fatighenti, Claudio Onorati

Given a vector bundle $E$ , we give an explicit formula to compute Chern classes of Schur bundles $S^{α} E$ in terms of those of $E$ .

Higher discriminants of vector bundles and Schur functors

Alessandro D'Andrea, Enrico Fatighenti, Claudio Onorati

We prove some closed formulas for the logarithmic Chern character of a locally free sheaf. The argument used is representation-theoretic and we connect these formulas with the acti…
