Abstract

Let H be a Hilbert space and B(H) the set of all bounded linear operators on H. In the paper we consider the generalized concept of order relations on B(H) which was proposed by Šemrl and which covers the star partial order, the left-star partial order, the right-star partial order, and the minus partial order. We also connect this concept with the sharp partial order.
