      Kingangi, Denis Njue (International Journal of Scientific and Innovative Mathematical Research (IJSIMR), 2015-08)
      Properties of operators in a C*-algebra B(H) have been studied by many researchers in operator theory. This paper is an investigation of the numerical ranges of operators in B(H) . We show that zero is in the algebraic ...
