Dear all, this is a reminder for the workshop Geometry in Modal Homotopy Type Theory at Carnegie Mellon University, Pittsburgh taking place March 11-15, 2019 PLEASE NOTE: The deadline for registration has been extended until the end of the week and there is now a list of participants on the workshop's website. Homotopy Type Theory (HoTT) is one of the tools to reason within a higher topos. The recent extensions of HoTT by modalities has led to stronger relations to the use of higher toposes in Topology, Differential Geometry and Algebraic Geometry. This workshop is about the development of Modal HoTT and its applications to Geometry. The invited speakers are: Peter Arndt Ulrik Buchholtz Eric Finster Egbert Rijke Urs Schreiber Mike Shulman For more information, see: http://www.andrew.cmu.edu/user/fwellen/modal-workshop.html All the best, Felix Wellen [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
