On some special cases of Gaiotto’s positivity conjecture. (English) Zbl 07912350
Summary: We prove a conjecture of D. Gaiotto on positivity of inner products arising in studying Landau-Ginzburg boundary conditions in the 1-dimensional case, and in special cases in higher dimensions, for 3d free hypermultiplets.
