Remarks on the Sequential Products

Mathematical Physics 2010-09-15 v1 math.MP

Abstract

In this paper, we show that those sequential products which were proposed by Liu and Shen and Wu in [J. Phys. A: Math. Theor. {\bf 42}, 185206 (2009), J. Phys. A: Math. Theor. {\bf 42}, 345203 (2009)] are just unitary equivalent to the sequential product AB=A12BA12A\circ B=A^{\frac{1}{2}}BA^{\frac{1}{2}}.
