Presheaves on 2-categories
Presheaves on categories crop up everywhere! In this talk, I'll give a gentle introduction to 2-categories, and discuss the notion of a presheaf on a 2-category. In particular, we'll consider which 2-categories such a presheaf might take values in. Only a little familiarity with the notion of a category will be assumed!

Representation growth vs subgroup growth (Held in ChCh, Tom Gate, Room 2)
The subgroup growth of finitely generated groups was seen last term, in a lecture of Dan Segal. This time, we see representation growth, and how it is similar to, and different from, subgroup growth.

A PID that is not Euclidean (Held in ChCh, Tom Gate, Room 2)
It is well-known that Euclidean domains are PIDs; examples proving that the inclusion is strict are not commonly known. Here is one.

Old theorems, new proofs: A week in fusion systems (HELD IN CHCH, Tom Gate, Room 2)
Last week, I proved five theorems about fusion systems, each with a (relatively) trivial proof. All of these theorems were known, but in each case the proof was (in some cases highly) non-trivial. I will introduce fusion systems and talk a bit about why they are interesting, and then prove some, or maybe all, of the theorems I proved.

How I learned to stop worrying and love automata (ChCh Tom Gate, Room 2)
In this talk, I shall endeavour to explain to the uneducated and uninitiated the joys and pleasures one can have studying automata.
