Resumen de An approach to operator Dunkl-Williams inequalities

F. Dadipour, Mohammad Sal Moslehian

• We prove several operator versions of the Dunkl�Williams inequality and discuss the case when equality holds in a new approach. We mainly present some necessary and sufficient conditions for the case where equality holds. We also deduce some norm inequalities and get a generalization of the Dunkl�Williams inequality in the framework of Hilbert C*-modules.
