Notice that we cannot hope to Σb1 -define all randomized p-time algorithms in S21 + dWPHP (PV ): by [48], this would imply that ZPP has a complete language, which is known to fail for a suitable relativized class ZPP A . We thus isolate a special subclass of randomized algorithms; the idea is, inste ...

If there already is a node in Nodes Set with the same obligations in both its Old and Next fields (line 5), the copy that already exists needs only to be updated w.r.t. its set of incoming edges; the set of edg ...

Views: Compositional Reasoning for Concurrent Programs

In a type system that permits strong (i.e. type-changing) updates, threads again have knowledge that variables agree with their types, but may make updates that change the typ ...

Löwenheim-Skolem Theorems, Countable Approximations, and L

Consequence relations and admissible rules

As this has more to do with consequence relations in general and the way in which they can be extended by rules, results about particular logics will be only discussed as illustration ...
