The article on supersymmetric Wilson loops does use product integrals in the sense relevant to this discussion it says on p 11 that it has presented a supersymmetric generalization of ordinary product integral formalism His primary reference for product integrals is Dollard and Friedman Product Integrals Addison Wesley 1979 and it seems like a lot of the paper is extending their formalism to the supersymmetric case And that s fine but it doesn t answer the question of notability of Grossman and Katz s work He doesn t mention them once nor does he seem to use any of their ideas Of course G K are strictly speaking off topic for this page this page is about multiplicative calculus in general not about their particular version of it
