Abstract

Furuta presented direct and simplified proofs of operator monotonicity of functions φ(t) = t - 1/log t and ψ(t) = t log t - t + 1/(log t) 2 by using Löwner-Heinz inequality. Extending his method, we give a sequence of operator monotone functions {fk(t)} k=0 with f0(t) = φ(t) and f 1(t) = ψ(t). We also study relations between fk(t) and strictly chaotic order defined among positive invertible operators and obtain some extensions of results due to Furuta.
