چکیده
|
We prove an operator arithmetic-harmonic mean type inequalityin krein space setting, by using some block matrix techniquesof indefinite type. we also give an example which shows that the operatorarithmetic-geometric-harmonic mean inequality for two invertibleselfadjoint operators on krein spaces is not valid, in general.
