Program slicing is a program transformation that is useful in program debugging, program maintenance, and other applications that involve understanding program behavior. Given a p...
We characterize the classes of functions computable by uniform log-depth (NC1) and polylog-depth circuit families as closures of a set of base functions. (The former is equivalent...
In a previous paper [4], we introduced a non-deterministic -calculus (-LK) whose type system corresponds exactly to Gentzen's cut-free LK [9]. This calculus, however, cannot b...
Abstract. In this paper, we provide a new approach to study undeniable signatures by translating secure digital signatures to secure undeniable signatures so that the existing algo...
Abstract. We answer a question asked by Hajdu and Tengely: The only arithmetic progression in coprime integers of the form (a2 , b2 , c2 , d5 ) is (1, 1, 1, 1). For the proof, we ï...
