We present a higher-order functional notation for polynomial-time computation with arbitrary 0; 1-valued oracle. This provides a linguistic characterization for classes such as np...
Singleton kinds provide an elegant device for expressing type equality information resulting from modern module languages, but they can severely complicate the metatheory of langu...
The web, as a real mass medium, has become an invaluable data source for Information Extraction and Retrieval systems. Digital authoring is a relatively new style of communication,...
Dependently typed lambda calculi such as the Logical Framework (LF) can encode relationships between terms in types and can naturally capture correspondences between formulas and ...
We prove several decidability and undecidability results for -PN, an extension of P/T nets with pure name creation and name management. We give a simple proof of undecidability of...
