Alessandro D'Andrea, Enrico Fatighenti, Claudio Onorati
Given a vector bundle , we give an explicit formula to compute Chern classes of Schur bundles in terms of those of .

A plethystic chain rule
Alessandro D'Andrea, Enrico Fatighenti, Claudio Onorati
We consider a derivation on the ring of symmetric functions and investigate its combinatorial, algebraic and geometric properties. More precisely, we show that $\…

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…
