Lieb type convexity for positive operator monotone decreasing functions
Published 2 Jun 2021 in math.FA | (2106.01095v2)
Abstract: We prove Lieb type convexity and concavity results for trace functionals associated with positive operator monotone (decreasing) functions and certain monotone concave functions. This gives a partial generalization of Hiai's recent work on trace functionals associated with power functions.
