    • New conditions for counteractivity of normality operators 

      Okelo, Bernad N.; Mogotu, P.O (2017-08)
      An interesting area in operator theory is the study of norm inequalities for Hilbert space operators. Many mathematicians have worked on this subject, for example in [2, 3 and 5]. On the other hand, contractive and ...

    • Norm bounds for contractive normality operators 

      Okelo, Bernad N.; Mogotu, P.O (2017-08)
      In this paper we establish the upper and lower norm estimates of contractive normaloid operators using inner product, Schwarz inequality for non-negative real numbers and some operator inequalities.
