### Categorical Semantics of Entropy

#### Posted by John Baez

There will be a symposium on the categorical semantics of entropy at the CUNY Grad Center in Manhattan on Friday May 13th, organized by John Terilla. Tai-Danae Bradley and I will give a tutorial on this subject on Wednesday May 11th. For both events you need to register to attend, either in person or via Zoom. All the talks will be recorded and made available later.

Details are below…

Thanks to some help from Francis, I’ve converted some of my conjectures on the classification of holomorphic $n$-gerbes into theorems!
