n-tuple groupoids and optimally coupled factorizations

Dany Majard

In this paper, we prove that the category of vacant $n$-tuple groupoids is equivalent to the category of factorizations of groupoids by $n$ factors that satisfy some Yang-Baxter type equation. Moreover we extend this equivalence to the category of maximally exclusive $n$-tuple groupoids, which we define, by dropping one assumption. The paper concludes by a note on how these results could tell us more about some Lie groups of interest.
