You mean, of course,
(A x B) # (C x D) ------> (A # C) x (B # D)
It has come up in my current student's dissertation work. An existing name and citations to papers using this specific type of duoidal category would be much appreciated.
I can't do much better than ``monoidal category with finite products''.
Any such becomes duoidal in this way.
Best wishes,
Ross
