20 - 22 September 2022, Proofs and Formalization in Logic, Mathematics and Philosophy , Utrecht

Date & Time: 20 - 22 September 2022, 09:30-16:00
Location: Utrecht
Costs: free

On 20-22 September the workshop Proofs and Formalization in Logic, Mathematics and Philosophy takes place at Utrecht University, the Netherlands.

The workshop aims to bring together researchers from various areas whose work either directly concerns the role of proofs or formalization in logic, mathematics and philosophy, or is relevant for these topics in a more indirect way, e.g. by being an example of the role proofs or formalization play in these fields.

There is no registration fee, but if you wish to attend (part of) the workshop, please send an email to Rosalie Iemhoff and Robin Martinot: , .

30 September 2022, Cool Logic, Mike Cruchten

Date & Time: Friday 30 September 2022, 17:00-19:00
Speaker: Mike Cruchten
Title: The theory of regular lasso languages
Location: Room TBA, ILLC, Science Park, Amsterdam

The theory of regular languages has been studied extensively and offers many nice connections to logic, algebra, and coalgebra. Unfortunately, the theory of omega-regular languages is slightly less well-behaved, in particular with regards to coalgebra. To bridge the gap we introduce the theory of regular lasso languages, a theory combining the simplicity of regular languages with the expressiveness of omega-regular languages. As with any other topic related to automata theory, plenty of pictures will be provided.
