Abstract
We prove an operator arithmetic-harmonic mean type inequality
in Krein space setting, by using some block matrix techniques
of indefinite type. We also give an example which shows that the operator
arithmetic-geometric-harmonic mean inequality for two invertible
selfadjoint operators on Krein spaces is not valid, in general.
