# The Categorical Late Lunch

## Edinburgh's informal category theory seminar

During the autumn semester of 2020 we are running an online category
theory seminar, fortnightly on Thursdays at 2pm (see schedule below).

The idea is for this seminar to be pretty low-key—a place where, for instance, grad
students feel comfortable giving an introduction to some standard
categorical topic. It's *not* intended to be a standard seminar where the norm is to describe your latest cutting-edge work.

We're hoping for a mixed group of participants, ranging from derived algebraic geometry to theoretical computer science, so talks should be accessible to anyone who knows some basic category theory. The aim is to create an informal environment, where questions and interaction during the talks are encouraged.

To keep things relaxed, this is for UoE + friends, and not
publicly accessible. For Zoom details, or to propose a topic, email Emily or Ruben.
