We present some new decision and comparison problems of unusually high computational complexity. Most of the problems are strictly combinatorial in nature; others involve basic lo...
Programs and Abstract Complexity A. Beckmann University of Wales Swansea Swansea, UK Axiom systems are ubiquitous in mathematical logic, one famous and well studied example being ï...
We employ the model-theoretic method of Ehrenfeucht-Fra sse Games to prove the completeness of the theory CFT, which has been introduced in 22] for describing rational trees in a ...
Ludics has been proposed by Girard as an abstract general approach to proof theory. We explain how its basic notions correspond to those of the "innocent strategy" apprao...
Abstract. Non-freely generated data types are widely used in case studies carried out in the theorem prover KIV. The most common examples are stores, sets and arrays. We present an...
