24th February – Philip Arathoon (University of Manchester): Flag manifolds
A natural collection of homogeneous symplectic manifolds is given by the orbits of the coadjoint action of a Lie group on the dual of its … Read more
17th February – Joe: Cluster’s first stand
Special types of cluster algebra arise from quiver mutation. In general these have infinitely many generators. Fomin and Zelevinsky provided a criterion for the finite … Read more
10th February – Giacomo: Characterising the Tangent Space
The tangent space to a smooth manifold is an important object in differential geometry. Depending on context, different ways of viewing this object can be … Read more
3rd February – Yoon: The Heun Equation and the Poincare-Perron Theorem
Heun functions generalize well-known special functions such as Spheroidal Wave, Lame, Mathieu, and hypergeometric-type functions. Heun functions are applicable to diverse areas such as theory … Read more
