The nine lemma in the S-Mal'tsev and in the S-protomodular settings
 
 
Description:  We investigate what is remaining of the nine lemma and of the denormalized nine lemma, respectively valid in a pointed protomodular and in a Mal'tsev category, in the context of partial protomodular and partial Mal'tsev categories, relatively to a class S of points. The results apply, among other structures, to monoids, semirings and quandles. Joint work with Dominique Bourn.
