Dr. Daniel Hausmann

About me
I am a postdoctoral researcher at the Chair for Theoretical Computer Science of the Friedrich-Alexander University of Erlangen and Nuremberg. Currently, I am working in the project Coalgebraic Model Checking (CoMoC) supervised by Stefan Milius and Lutz Schröder.
I am interested in e.g.
-
general fixpoint theory
-
automata on infinite words
-
solving two-player games
-
the algorithmics of temporal logics (e.g. model and satisfiability checking for branching-time and linear-time logics)
-
coalgebra and coalgebraic logic
My PhD-thesis Satisfiability Checking for the Coalgebraic µ-Calculus (supervised by Lutz Schröder) gives a detailed discourse on decision procedures for the satisfiability problem of general modal fixpoint logics.
We have implemented various satisfiability and model checking algorithms for the coalgebraic µ-calculus within COOL.
