The KCL/UCL Junior Geometry Seminar is a joint seminar of King's College London and University College London, presenting topics from Algebraic Geometry, Differential Geometry, Geometric Analysis, Geometric Group Theory, Topology, and related areas.
The target audience is young researchers — in particular PhD students — with the goal of being useful to those that attend. Talks can be introductory, or more advanced. All sessions of this seminar are held on Mondays at King's College in room (TBD) on Tuesdays from 16:00 to 17:00 , and snacks will be provided. If you would like to see a particular topic, or give a talk, please email one of the organizers:
- Simon Alonso (s.alonso24@imperial.ac.uk)
- Zhaoyang Liu (Zhaoyang.1.liu.24@kcl.ac.uk)
- Fulin Zhong (fulin.zhong.24@ucl.ac.uk)
The format of this seminar is slightly different from the usual weekly talk one. This year we will have one expert speaker every three weeks (or exceptionally two) and hold two preparatory sessions (or exceptionally only one) on the subject of the expert talk. These sessions will be cooperative and revolve around discussions and questions asked by the expert. The two preliminary sessions will sometimes start with a brief exposition of the questions by the chair of the session but their goal is to encourage discussions and exchange. Whether you already know a lot about the subject or you are simply curious to learn about it, you are very welcome to attend : the diversity of point of views is very precious when learning maths !
This seminar is run in parallel with the Imperial Junior Geometry Seminar , which features one talk every week, and we strongly encourage everyone to attend both.

Title: Grassmannians as Homogeneous Varieties: From Algebraic Groups to Lie Theory
Speaker: Zhaoyang Liu (LSGNT)
Tuesday 14th October, 16:00pm–17:00pm, Bush House(S)4.03 KCL
In this talk, we will view the Grassmannian not merely as a parameter space of linear subspaces, but as a homogeneous variety under the action of an algebraic group. We will start with a brief overview of algebraic groups and their basic properties, and then introduce the notion of homogeneous spaces. The motivation for this perspective will be discussed, highlighting how it connects the geometry of varieties with the structure theory of Lie groups and Lie algebras. Time permitting, we will also touch on some classical examples illustrating the interplay between algebraic and differential viewpoints.

Title: Introduction to Grassmannians
Speaker: Simon Alonso (LSGNT)
Tuesday 7th October, 16:00pm–17:00pm, BH(SE) 1.02 KCL
The aim of this session is to prepare for Zhaoyang's talk about Grassmannians next week. We are therefore going to go on a walk through different ways to think about Grassmannians and a collective reflexion on why do we care about them. Informally, the goal is to decide on Zhaoyang's title and abstract so dont hesitate to come and share your point of view.
