A Logic for PTIME and a Parameterized Halting Problem
In [7] Nash, Remmel, and Vianu have raised the question whether a logic L, already introduced by Gurevich in 1988, captures polynomial time, and they give a reformulation of this ...

On Metric Temporal Logic and Faulty Turing Machines
Metric Temporal Logic (MTL) is a real-time extension of Linear Temporal Logic that was proposed fifteen years ago and has since been extensively studied. Since the early 1990s, it ...

A logical account of pspace
We propose a characterization of PSPACE by means of a type assignment for an extension of lambda calculus with a conditional construction. The type assignment STAB is an extension...

On the Complexity of Unary Tiling-Recognizable Picture Languages
Abstract. We give a characterization, in terms of computational complexity, of the family Rec1 of the unary picture languages that are tiling recognizable. We introduce quasi-unary...

On the Expressibility of Stable Logic Programming
Schlipf (Sch95) proved that Stable Logic Programming (SLP) solves all NP decision problems. We extend Schlipf’s result to prove that SLP solves all search problems in the class ...
