Lemma 82.29.1. In Situation 82.2.1 let X/B be good. Let \mathcal{E} be a finite locally free sheaf of rank r on X. Let \mathcal{L} be an invertible sheaf on X. Then we have
82.29.1.1
\begin{equation} \label{spaces-chow-equation-twist} c_ i({\mathcal E} \otimes {\mathcal L}) = \sum \nolimits _{j = 0}^ i \binom {r - i + j}{j} c_{i - j}({\mathcal E}) c_1({\mathcal L})^ j \end{equation}
in A^*(X).
