Summary: We prove a linear extension theorem for continuous finite measures on preduals of von Neumann algebras. Making use of it, we determine the structure of surjective positive linear isometries between non-commutative L^p-spaces associated with arbitrary von Neumann algebras.
Keywords: von Neumann algebra, non-commutative L^p-spaces.
