Seminars in Pure Mathematics

Pure Mathematics Seminars are held at 2:00pm on Tuesdays in room 119 of the Michael Atiyah building (unless otherwise stated below). They are usually preceded by lunch at 12:30 in the Charles Wilson building, and followed by tea and biscuits in College House. All are welcome to these seminars. For any questions or comments please contact Andy Tonks at

2016-2017 Leicester Pure Mathematics Seminar (Semester 1)

04/10/2016 Giuseppe Tinaglia (King's College, London) The geometry of constant mean curvature surfaces in Euclidean space

Abstract: In this talk I will begin by reviewing classical geometric properties of constant mean curvature surfaces, H>0, in R^3. I will then talk about several more recent results for surfaces embedded in R^3 with constant mean curvature, such as curvature and radius estimates for simply-connected surfaces embedded in R^3 with constant mean curvature. Finally I will show applications of such estimates including a characterisation of the round sphere as the only simply-connected surface embedded in R^3 with constant mean curvature and area estimates for compact surfaces embedded in a flat torus with constant mean curvature and finite genus. This is joint work with Meeks.

11/10/2016 Artie Prendergast-Smith (Loughborough) Cones of positive classes

Abstract: I will explain why convex cones of "positive" cohomology classes arise naturally in algebraic geometry, why they are important, and some things we know about them.
