Abstract: 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.
Keywords: gauge theory, total positivity, positive definite function, Bochner's theorem.
