Questions regarding the creation of commutative diagrams. Use this tag if you can't find a more specific tag for [one of these packages](https://www.ctan.org/topic/diagram-comm).
A commutative diagram is a way of organizing objects and functions in mathematics, particularly in category theory, abstract algebra, geometry, and topology. Here, the name "commutative diagram" does not imply any commutativity relations between the arrows, but just refers to the style of diagram; if your diagram isn't in this style, use the broader diagrams tag instead.
There are several packages available for typesetting commutative diagrams, including xy-pic and tikz-cd (the most popular), as well as
ams-cd and several others listed here; if your question involves a specific package, use that package's tag instead of this one.
