Since its start on November 1999, the workshop series on Games, Logic, Language and Computation (GLLC) has brought together researchers from diverse fields, like logic, informatics, social sciences and humanities, with the aim of discussing connections within these different areas under the occasion of dissertation defenses on major themes.
The theme of this 21th GLLC edition is Modalities, Coalgebra, Complexity and Interaction , and it will bring together researchers working at the interface between these fields. The workshop will be hosted by the Institute for Logic, Language and Computation (ILLC) of the Universiteit van Amsterdam (UvA) on the occasion of the defense of the PhD dissertations Complexity in Interaction by Lena Kurzen and Modalities Through the Looking Glass: A study on coalgebraic modal logic and their applications by Raul Andres Leal.
The workshop will take place in Nina van Leerzaal at Allard Pierson Museum – Oude Turfmarkt 127, from 9:30 to 17:30, with the following program:
