 in $\prod_{p \geq 0} A^p(Y)$.
 In turn, it suffices to prove this after restricting
 to a connected component of $Y$. Hence we may assume
-the complexes $\mathcal{E}_1^\bullet$ \and $\mathcal{E}_2^\bullet$
+the complexes $\mathcal{E}_1^\bullet$ and $\mathcal{E}_2^\bullet$
 are bounded complexes of finite locally free $\mathcal{O}_Y$-modules
 of fixed rank. In this case the desired equality follows from the
 multiplicativity of Lemma \ref{lemma-additivity-chern-classes}.
