On power means of positive quadratic forms

Erwin Lutwak

Research output: Contribution to journalArticlepeer-review


Some power means of positive definite quadratic forms are closely related to the fundamental scalar functions of the matrix associated with the quadratic form. This relation can (among other things) be used to give new proofs of some of the classical matrix inequalities.
