Quiver Brascamp–Lieb inequalities

Nicholas Hu

Vol. 333 (2024), No. 1, 115–126
Abstract

We formulate generalized Brascamp–Lieb inequalities for representations of bipartite quivers and establish necessary and sufficient conditions for such inequalities. Notably, we show contra Lieb that Gaussians do not saturate certain types of quiver Brascamp–Lieb inequalities.
