Computational models allow us to reason about programs by abstracting their operatingprocess. The choice of a suitable model for a given situation takes into account both itsexpressivity and properties such as the complexity of the associated problems. This thesisstudies computational models in order to develop tools for conception and analysis ofprograms.First we consider the language equivalence problem for automata, which has variousapplications especially in the formal verification field. Our starting point is a coinductivealgorithm HKC developed by Bonchi and Pous that exploits up-to techniques to comparefinite automata. We present a version of this algorithm that works in a slighty extendedsetting, so we can adapt it to Büchi automata...
