Normally, Glen's module is completed in the first term of each year. One should the consider, in order of priority, the following options.
1. To import the module via VC.
2. Arrange for attendance of our interested students to the London PhD School.
To have it delivered either of these ways is impossible this year, of course.
However, if a sufficient number of students are interested, one could gently approach Glen and ask him whether he would like to repeat it. Alternatively, a combination of Glen's book and completion of the problem sheets should be sufficient to learn the subject. In this case, though, students should set aside time for self-tutoring.
Thanks to Declan Millar for some heads-up on the matter !
