French exams

Posted by Martin Orr on Saturday, 20 March 2010 at 22:45

In the past six weeks I have taken four exams: two on the courses from the first semester (October-January) and two on the courses I have taken January-February. The reason the latter came so soon after the former is because they are in different institutions - the first two were here in Orsay, the second two in other institutions in Paris with different timetables. These exams were hard, and very different from exams in Cambridge. (Note: this post discusses pure maths exams only.)

Representations of algebraic tori

Posted by Martin Orr on Wednesday, 03 March 2010 at 10:08

I am finally ready to finish my series on algebraic tori, by talking about their representations. I shall show that these representations can be classified by a grading on the vector space of the representation, after extending scalars to the separable closure. I will describe this classification explicitly in a simple case.
