Abstract. Recently, development of peer-to-peer (P2P) applications has been giving a paramount attention mostly due to their attractive features such as decentralization and self-o...
We show that if a language L has a 4-round, black-box, computational zero-knowledge proof system with negligible soundness error, then ¯L ∈ MA. Assuming the polynomial hierarch...
Constraint solvers are key modules in many systems with reasoning capabilities (e.g., automated theorem provers). To incorporate constraint solvers in such systems, the capability ...
We prove that QIP(2), the class of problems having two-message quantum interactive proof systems, is a subset of PSPACE. This relationship is obtained by means of an efficient pa...
This paper presents simple, syntactic strong normalization proofs for the simply-typed -calculus and the polymorphic -calculus (system F) with the full set of logical connectives, ...
