Definition 86.15.2. Let $\varphi : A \to B$ be a continuous ring homomorphism between adic Noetherian topological rings, i.e., $\varphi$ is an arrow of $\textit{WAdm}^{Noeth}$. We say $\varphi$ is naively rig-flat if $\varphi$ is adic, topologically of finite type, and satisfies the equivalent conditions of Lemma 86.15.1.
