  • Abstract
    Consideration is given to polynomial-time machines. Among these classes are EP and PP. The authors prove PEP[log] 25 PP, investigate the Boolean closure BC(EP) of EP, and give a relativization principle which allows them to completely separate BC(EP) in a suitable relativized world and to give simple proofs for known relativization results. Further results concerning the relationships of such classes in unrelativized and relativized worlds are given
