Abstract
Let A and B be f -algebras with unit elements eA and eB respectively. A
positive operator T from A to B satisfying T(eA) = eB is called a Markov
operator. In this definition we replace unit elements with weak order units
and, in this case, call T to be a weak Markov operator. In this paper, we
characterize extreme points of the weak Markov operators.
