Is there already a name in the literature for the special instance of duoidal category in which one of the monoidal structures is cartesian? In particular the instance in which if # denotes the non-cartesian monoidal structure and x the cartesian, the lax middle-four interchange transformation has components (A x B) # (C x D) ------> (A # B) x (C # 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.
