Created double pushout rewriting and pushout complement, and added a relevant lemma to adhesive category.
Generalized (and renamed) double pushout rewriting to span rewriting, along the way creating final pullback complement and adding another property to adhesive category.
Good to see these entries! The carrying out of local moves in knot theory can essentially be seen as an example of double pushout rewriting, which I find very interesting and quite insightful: a year or two ago I came up with a categorical formulation of local moves in knot theory for some work I was doing at the time, and when discussing it with Richard Garner, he pointed out to me that what I was doing was basically double pushout rewriting.
That’s neat! Do you have any precise statement that you could add to the page?
Yes, I can try to add something when I get the chance.
