The upcoming talk
At the next session of the TCS,
on the 22nd of January 2025,
at 2:15 – 4:15 p.m. CET / 3:15 – 5:15 p.m. EET
Peter Kristel
(Universität Greifswald)
shall give us
“An Eclectic Excursion into 2-Categorical Geometry“.
Abstract
I will give a gentle introduction into 2-categorical geometry by introducing 2-categorical generalizations of fundamental objects appearing in classical differential geometry. Prime examples of such objects being vector spaces, groups, line bundles, and vector bundles. I will take a phenomenological approach to these topics, focusing on concrete descriptions and taking String Geometry as an organizing and motivating example.
