More or less a vague reference request: do you recommend some articles or books which (somehow) treat categories in the style of “combinatorial group theory”, in particular, developing notation for “relators” and results on “finitely presented” categories (both in the sense of combinatorial group theory).
For obvious reasons, every book on combinatorial group theory, and many articles within semigroup theory are something in that direction, but the question is rather asking for a more category-theoretic treatment.
Something of a moderate extension of combinatorial group theory to (some classes of) categories?
]]>Hi,
It seems, that the reference pdf is dead on page Kirchhoff’s laws. Could somebody update it?
Thanks,
