AGGITatE 2025: Groups, Representations and Cohomology

AGGITatE 2025 will take place at the University of Essex 4-7th August 2025 and focus on Groups, Representations and Cohomology.  The conference is funded by the London Mathematical Society and the Heilbronn Institute. AGGITatE is an annual workshop taking place at the University of Essex. Its aim is to bring together researchers working in algebraic geometry and algebraic groups. It has run in 2022, 2023 and 2024.

Registration

Please, fill in the registration form if you want to attend. You must register by 30th June and if you want to be considered for funding you must register by 31st May.

There will be a registration fee of around £40 for all participants, to be paid after we confirm your attendance (to be paid later on in June).

Logistics

Arrival date is Sunday 3rd August. The Conference will start on Monday 4th August in the morning and finish at about 3.00pm on 7th August. We have 12 single ensuite rooms with shared kitchen facilities, booked for 4 nights (Arrival Sunday 3rd, checking out Thursday 7th August). These are prioritised for early-career UK-based participants due to funder’s conditions. If you want to be considered for accommodation, please clearly indicate it in the form.

Transportation: The University of Essex is based in Colchester. Find here a map of the university of Essex. Please, consult the university’s website on how to reach Colchester Campus. The closest railway station is Colchester Hythe, but Colchester North (AKA as Colchester, which is different from Colchester Town) is the one with the best connections. If you use buses, please be aware they can be unreliable, so leave extra time when using them. The closest airport is Stansted and it is best connected to Colchester by bus. Travelling from Gatwick or Stansted by train is not too long (2-3 hours). The cost of a taxi within Colchester is usually £10-15. There are a number of companies (google ‘Colchester taxi’ for a list) that operate independently from each other and the best way to arrange a taxi is to call them directly. It is very difficult to book a taxi at around school ‘rush hour’ or early in the morning, unless arranged in advance.

Wednesday afternoon: we will not have scheduled lectures. However, we have a couple of activities that you can take part on: a visit of Colchester (the oldest recorded town in the United Kingdom, founded by the Romans) or a Disc Golf game. The University of Essex is the home of the first Disc Golf course in England and the eighth oldest in the world. It has been recently redesigned.

Conference dinner: We will have a conference dinner on Tuesday.

Rooms: We have book rooms NTC 2.05 and NTC 2.06 for the conference.

Accommodation: If your accommodation is paid by the organisers, we will be in touch with details.
If you are self-funded, the following are good options for accommodation in Colchester. All are in the route of buses 62 and 62B which take you directly to Campus in about 20 minutes. You can also walk to campus in 40-60 minutes, depending on the hotel.

On the AGGITatE series

The first AGGITatE conference was to take place in 2020 but was delayed to 2022 due to the CoViD panemic and, back then it stood for “Algebraic Groups and Geometric Invariant Theory at Essex” as a way to bring together researchers working in algebraic groups and algebraic geometry. The second AGGITatE took place in 2023, focused in algebraic groups and the Cremona group. The third AGGITatE (2024) was focused on moduli theory of varieties. The fifth edition of AGGITatE (2026) will be part of a one-month INI Satellite Programme.
