Teaching

• Notes for a course on Algebraic Groups.
• Notes for Finite groups of Lie type: Notes on algebraic groups, Rational structures over finite fields, Notes on GL_n.
• Notes on character sheaves: pdf, a somewhat more sophisticated outline of some aspects of character sheaves - typos probably abound.

• Classical Groups, notes.: this course gave an elementary discussion of the Classical groups, focusing on the general linear group.
• Integration in R^n, notes: these notes give an account of Riemann Integration in R^n, getting as far as an elementary discussion of the integration of differential forms on surfaces.
• Surfaces in R^n, notes: these notes describe the theory of manifolds embedded in R^n up to Stokes' theorem.
