In autumn, we will have one lecture a week for approximately 90 minutes from 3 pm which will be delivered live online by a geometry faculty member from King's, UCL or Imperial. In the spring, the course will be divided into two strands. The students should only attend one of these strands and the assessment will reflect that. Attending to both strands is likely to be overwhelming but is allowed. The lectures will be hosted at our server running the open source software Big Blue Button. The link to each lecture and the acccess code will be shared with you on the day of the lecture. In addition, there will be a wrap-up session the following Friday between 11am - 1pm to go over exercises, examples, things you didn't understand, etc. This will also be online. One student will own each topic and be responsible for finding people to present examples in the wrap-up session. That person will also supervise the wrap-up session for the 1st year students next year. The owner gives a short lecture or summary at the start of the wrap up, and also produces notes of the lecture in TeX. Every week you will receive a set of exercises based on the course material. Doing exercises yourself is the most important part of this course. Do as many which challenge you as you can. Please solve at least one each week and send a pdf to Nicky within 10 days of the lecture. Senior PhD students will give you feedback on your solutions. Don't choose the easiest one (unless it challenges you). Don't only write up exercises that you can do. It is fine to write up something you got stuck on, saying what you tried or why you're stuck. It's also fine to write up something completely different -- your own exercise or an extension of something in the lecture. Previously this course was arranged by a Richard Thomas. There is an impressive amount of useful information and good advice in the previous website which you should check out by clicking this. (I have freely moved some of the content from there to this website but some good advice by Richard remains on his website.) There are also Junior Geometry Seminar at Imperial organized by Jaime Roche, John McCarthy and Mohammed Shafi and Junior Geometry Seminar at UCL/KCL organized by Alessio Di Lorenzo, Ivan Solonenko and Tom Sharpe, which meet weekly and cover supplementary topics.
There is a Matrix chat room associated with this course. You can access it by creating an account at the Freemath chat server (make sure to choose Other so that your account is created in freemath.xyz) and joining the room called Topics in Geometry. This is a platform for informal discussions related to the course among the participants. I will be available and happy to chat about the topics of this course in an asynchronous manner.
Here are some of the topics that may be covered in this course. Some of these were taught in the past years and you can get the previously produced notes associated with these lectures by clicking the links.
