Abstract
Young’s inequality in two variables is formulated so as to apply to positive Hilbert space operators. The Young-type operator inequalities herein occur in the context of von Neumann algebras, and apply to the singular numbers, the spectral preorder, and traces of positive operators. As an application, a Young inequality relative to tracial states on unital C∗-algebras is obtained and, if the tracial state is faithful, the cases of equality are completely determined.
