Jensen's inequality for partial traces in von Neumann algebras
Journal article, 2026
Motivated by a recent result on finite-dimensional Hilbert spaces, we prove Jensen's inequality for partial traces in semifinite von Neumann algebras. We also prove a similar inequality in the framework of general (non-tracial) von Neumann algebras.
