Operator norms of words formed from positive-definite matrices
Main Article Content
Let α1,α2,...,αn,β1,β2,...,βn be strictly positive reals with α1 +α2 +···+αn = β1 + β2 +···+ βn = s. In this paper, the inequality
when A and B are positive-deﬁnite matrices is studied. Related questions are also studied.
