Abstract
Let be a complex Hilbert space with and the positive cone of the algebra of all bounded linear operators on . For , is called a positive truncation of if , where denotes the orthogonal projection onto the closure of . We determine structures of all bijections preserving the positive truncations of operators in both directions on the positive cone .
