Motivated by results on interactive proof systems we investigate an 3-V-hierarchy over P using word quantifiers as well as two types of set quantifiers. This hierarchy, which extends the (arithmetic) polynomial-time hierarchy, is called the analytic polynomial-time hierarchy. It is shown that every

In a previous paper the present authors (Baier and Wagner, 1996) investigated an S-V-hierarchy over P using word quantifiers as well as two types of set quantifiers, the so-called analytic polynomial-time hierarchy. The fact that some constructions there result in a bounded number of oracle queries
## Abstract We show that the bounded arithmetic theory V^0^ does not prove that the polynomial time hierarchy collapses to the linear time hierarchy (without parameters). The result follows from a lower bound for bounded depth circuits computing prefix parity, where the circuits are allowed some au
