Remark 42.34.2. Let $(S, \delta )$ be as in Situation 42.7.1. Let $f : Y' \to Y$ be a morphism of schemes locally of finite type over $S$. As a special case of Remark 42.33.5 there is a canonical $\mathbf{Z}$-algebra map $res : A^*(Y) \to A^*(Y')$. This map is often denoted $f^*$ in the literature.
