RSS Meetups are monthly gatherings of LASIGE members with research interests mainly in Software Architecture, Verification, Testing, Programming Languages, Type Systems, Logic, Concurrency, and Formal Methods.

Title: The Different Shades of Infinite Session Types. Part 1: Black and White
Speaker: Vasco T. Vasconcelos (LASIGE, DI-FCUL)
When: Tuesday, February 23, 14h30
Where: https://videoconf-colibri.zoom.us/j/82972397677

Abstract: 
There are different shades of types, session types in particular. On the one end there is darkness, the world can only be grasped at an arm’s length. One can move one step forward but that will only yield another arm’s length of understanding. The world remains finite, inductive. At the other extreme there is absolute light; one can see at unimaginable distances and beyond. This is the infinite, coinductive world. We study important properties of session types and processes in these worlds, such as type formation, process reduction, and soundness. [Joint work with Simon Gay and Diogo Poças]
