条件(Q)条件(P_T)对推出图及Rees商的传递性

The transmission characteristic of pushout and rees quotient condition (Q) and (P_T)

研究了条件(Q)、条件(PT)对推出图、Rees商的传递性,证明了在推出图(1)中P满足条件(Q)当且仅当Y满足条件(Q)并且f是酉的.

In this paper, we mainly study the thansmission characteristic of condition (Q) and condition (PT) to the pushout diagram and rees quotient, then present that in the diagram (1) when P satisfies condition (Q) if Y satisfies condition (Q) , f is unitary.
