My YouTube Channel: Adventures in Pure Mathematics

If you know the basic language of pure mathematics (i.e. what's a group, ring, topological space), then you may be interested my Youtube channel videos which give snapshots of more advanced pure mathematics. These adventures in pure mathematics are mostly aimed at honours students, and more generally, anyone who has completed MATH3711 and MATH3611. The goal is to present important ideas and results in mathematics without the burden of going through heavy duty proofs. For the latter, you just need to do the hard work.

Here are some preprints.

In 2010, I gave a series of lectures on the theory of orders. The main purpose was to provide details on ramification theory so that one can read papers on recent work on concerning orders on surfaces. These LECTURES ON ORDERS have been typed up by Boris Lerner and should be appropriate for graduate students.

Extension III Mathematics

This is an informal self-paced course for talented high school students who have finished the secondary school curriculum early and want to be extended before entering university. It is particularly aimed at students who found Extension 2 mathematics easy and want exposure to new mathematics in a much more explorative format.
