Let $G$ be a discrete group and $X$ a $G$-set. The equivariant category $X//G$ has elements of $X$ as objects, each triple $(g,x,g\cdot x)$ defines a morphism $x \to g\cdot x$, the composition corresp …

Expanding on Dylan Wilson's answer, condition (2) is indeed just a continuation of $\mathbb{G}_m$-action to an $\mathbb{A}^1$-action, since $\mathcal{O}(\mathbb{A}^1) \hookrightarrow \mathcal{O}(\math …
