Let Y_{i}$Y_{i}$ be infinitely many reduced closed subschemes of a smooth scheme X$X$ over an algebraically closed field. Suppose that they have a point y$y$ in common and y$y$ is closed in X$X$. Let Z$Z$ be the intersection of Y_{i}$Y_{i}$'s in X$X$. What is the relation between Spf(hat{Z}{y}) and Spf(\hat{Y{i}}_{y})$\operatorname{Spf}(\hat{Z}_{y})$ and $\operatorname{Spf}(\hat{\left(Y_{i}\right)}_{y})$? Here, \hat{A}{a}$\hat{A}_{a}$ refers to the completed stalk and Spf$\operatorname{Spf}$ denotes the formal spectrum.
