Can you explain more about the map $R:\operatorname{SE}(2)\rightarrow \operatorname{Diff}(\mathbb{R}^2)$? I have not yet caught up with the idea.

Thank you all. I have already answered my question myself in a way a little different from Chik67's below.

@BenMcKay: The action $R$ is given by $\mathcal{A}$ included in my question.

Thank you @DeaneYang. For the purpose of the article, the author wants to use differentiation. Unfortunately, this is the first time I've seen this representation.

Thank you. $R_{\left(\gamma,\theta\right)}$ is an action of $SE\left(2\right)$ with the translation $\gamma$ and the rotation $\theta$.
