Remark 37.9.3. Assumptions and notation as in Lemma 37.9.2. The action of a local section $\theta $ on $a'$ is sometimes indicated by $\theta \cdot a'$. Note that this means nothing else than the fact that $(a')^\sharp $ and $(\theta \cdot a')^\sharp $ differ by a derivation $D$ which is related to $\theta $ by Equation (37.9.1.1).
