   Format: MarkdownItexadded to _[[tangent complex]]_ pointer to the article [Hennion 13](https://ncatlab.org/nlab/show/tangent+complex#Hennion13), which proves, among other things, that at least in the generality of derived algebraic stacks, the tangent complex is sections of the [[infinitesimal disk bundle]] (i.e. the formal completion of the diagonal).
