Johannes Marti

I am a postdoc at the ILLC in Amsterdam working with Yde Venema on cyclic proof systems for modal fixpoint logics.

Before, I did postdocs with Carsten Lutz in the Theory of Artificial Intelligence group at the University of Bremen and with Clemens Kupke in the MSP group at the University of Strathclyde in Glasgow.

I completed my dissertation under the supervision Martin Stokhof and Frank Veltman also at the ILLC. My PhD thesis is on representation theorems for possible world models of belief and meaning with respect to linguistic behavior.


On fixpoint logic:

On coalgebraic modal logic, partially based on my MSc thesis:

On description logic:

On nonmonotonic and conditional logic:

On epistemic game theory:
