Published results show that various models may be obtained by combining parallel composition with probability and with or without non-determinism. In this paper we treat this probl...
Various feature descriptions are being employed in constrained-based grammar formalisms. The common notational primitive of these descriptions are functional attributes called fea...
Harvey Friedman introduced natural independence results for the Peano axioms via certain schemes of combinatorial well-foundedness. We consider here parameterized versions of this...
: Automated deduction systems can considerably be improved by replacing axioms with special purpose inference mechanisms. For example replacing in resolution based systems certain ...
It is proved that the forcing apparatus can be built and set to work in ZFCA (=ZFC minus foundation plus the antifoundation axiom AFA). The key tools for this construction are gre...
