This papers presents an overview of the specification and implementation of an exception handling system initially conceived [3] for the Lore Object Oriented Language and adapted to Smalltalk [4] The key ideas of this system are (1) to apply object oriented design to the whole system, to define a reusable and open class library for exception handling allowing systems designers to reuse it to produce dedicated exception ....

....K. Some straightforward relations among the defined classes are BPP PP, and PhiP P PP . It is also known that P PhiP = PhiP [16] and that P BPP =BPP [32] i.e. PhiP and BPP are closed under polynomial time Turing reducibility. There are relativizations separating all three classes [4,17,26]. Based on the class PP, and in a similar way as it is done with NP in PH, it is possible to define a hierarchy of complexity classes (PP, PP PP : which is called the counting hierarchy [25,29] Classes as operators Based on the definition of certain language classes, it can be useful ....
....FewP. The difference is that here the exact number of accepting paths for machine M on an input x is not known, but it depends on integer ff x . There are relativizations under which a result like theorem 8 cannot be achieved for the case of classes with an unbounded number of accepting paths [26]. However the above result is strong enough for proving the lowness of PhiP for P PP . Theorem 21: 23] PhiP is low for P PP . Proof: We show that PP PhiP is included in P PP . The result follows taking the Turing reducibility closure of both classes. Let L be a language in PP PhiP ....
