Next Meeting
Imperial College, London - 19th March 2026
The next meeting of the COW will take place on Thursday 19th March 2026 at Imperial College, London. The meeting will start at 1pm and finish at 5pm.
Speakers:- Kento Fujita (Osaka)
- Giulia Gugiatti (Edinburgh)
- Rahul Pandharipande (ETH Zurich)
For those who do not wish to attend the meeting in-person, we also plan to broadcast talks live using Microsoft Teams. Information about how to join the Teams meeting will be circulated to the COW mailing list the day before the meeting. If you would like to join the COW mailing list, instructions on how to do so may be found on the mailing lists page. If you would like to attend the meeting remotely but do not want to join the mailing list, please send an email to Alan Thompson (A.M.Thompson (at) lboro.ac.uk) requesting the meeting information.
Schedule
All talks will take place in room 140 in the Huxley Building.
| Time | Speaker | Title |
| 1:00pm | Rahul Pandharipande | GW/DT in families |
| 2:30pm | Kento Fujita | Elementary links from prime Fano 3-folds along 2 lines |
| 3:50pm | Giulia Gugiatti | Kuznetsov components in mirror symmetry |
Funding and Travel Claims
The COW has some funding to cover travel expenses for UK-based PhD students and postdocs. The COW is currently funded by the Isaac Newton Institute and the Heilbronn Institute for Mathematical Research under the UKRI/EPSRC Additional Funding Programme for Mathematical Sciences (EPSRC EP/V521917/1) and by the London Mathematical Society under a scheme 3 grant.
To ensure that we can fund as many participants as possible, we ask that participants purchase "advance" or "off-peak" train tickets where practical, and non-travel expenses (e.g. accommodation, food) cannot be covered. For those under the age of 30, we also recommend looking into getting a railcard, which can offer substantial savings on the cost of train travel around the UK. Information about how to submit a claim is available on the COW homepage here.
Abstracts
- Rahul Pandharipande (ETH Zurich) - GW/DT in families
- I will explain aspects of the GW/DT correspondence for families of 3-folds with applications to the enumerative geometry of Hilbert schemes of points, K3 surfaces, and abelian varieties. At the moment, there are few techniques available to attack the families correspondence, so much (but not all) of the theory is conjectural. The talk represents joint work with Iribar Lopez, Oberdieck, Pixton, and H-H Tseng.
- Kento Fujita (Osaka) - Elementary links from prime Fano 3-folds along 2 lines
- This work is motivated by the work Dubouloz-Fujita-Kishimoto about an alternative proof for the classification of prime Fano threefolds of genus 12 with infinite automorphism groups, firstly proved by Kuznetsov-Prokhorov-Shramov. In the paper of DFK, in order to analyze the automorphism groups of such X such that Aut(X) contains the multiplicative group Gm, they consider the blowup of X along the Gm-invariant 2 lines. In this talk, I would like talk about generalizations of the idea without assuming Aut(X) infinity group nor genus 12.
- Giulia Gugiatti (Edinburgh) - Kuznetsov components in mirror symmetry
- In this talk I will explore how the structural features of Kuznetsov components of Fano varieties are reflected in the geometry of their mirror Landau-Ginzburg models. I will focus on Fano varieties arising as branched covers along Calabi-Yau hypersurfaces and propose a mirror description of their Kuznetsov component. I will discuss the case of the quartic double solid in detail. The talk is based on work in progress with Ilaria Di Dedda, Danil Kozevnikov, and Nick Sheridan.
