Calf Seminar
About the Calf
Calf is the junior COW, an algebraic geometry seminar group primarily aimed at PhD students.
The organisers for academic year 2020/21 are Calla Tschanz (Bath), Geoffrey Mboya (Oxford) and Joe Prebble (Loughborough), and we have an extensive network of local organisers at different universities. Calf announcements are made using the COW mailing list. If you would like to get involved in the organisation, or suggest your institution as the next venue, please contact either of the people named above.
The COW seminar has some funding for travel expenses, and information on reimbursement can be found on the main COW webpage.
Due to the current situation with COVID-19, we are organising a series of online seminars via Zoom. The link to join will be in an email announcement made via the COW mailing list. If you do not have the link and wish to attend, please email one of the organisers.

Title: Foliations and Birational Geometry
Abstract: In a single breath, a foliation is a partitioning of a manifold into submersed submanifolds all of the same codimension, called the leaves of the foliation.
In this talk we'll explore holomorphic foliations from a birational point of view. The main case is surface foliations, which are defined simply by holomorphic differential equations on the plane.
But instead of going about solving these equations to find particular solutions, our interest is in a qualitative understanding of the geometry of a foliation.
There'll hopefully be many examples to display the different geometric behaviours, like the geometry of the leaves or the holonomies around singular points.
In this way we can try to abstract out features shared among groups of foliations, for the purpose of a classification that in the surface case very much resembles the classical Kodaira-Enriques classification.
The goal towards the end will be to explain one major helpful tool in this direction: The development of a Minimal Model Program foliations.
