  • 摘要:

    The ordering principle states that every finite linear order has a least element. We show that, in the relativized setting, the surjective weak pigeonhole principle for polynomial time functions does not prove a Herbrandized version of the ordering principle over T12. This answers an open question raised in [Buss, Ko{\l}odziejczyk and Thapen, 2012] and completes their program to compare the strength of Je\v{r}\'abek's bounded arithmetic theory for approximate counting with weakened versions of it.
