Courses Taught at the University of British Columbia

 

Courses Taught at Harvard University

  • Mathematics 129. Number Fields, Spring 2009       Algebraic number theory: number fields, unique factorization of ideals,
    finiteness of class group, structure of unit group, Frobenius elements,
    local fields, ramification, weak approximation, adeles, and ideles.

  • Mathematics 152. Discrete Mathematics, Fall 2008
    An introduction to finite groups, finite fields, finite geometry,
    discrete probability, and graph theory. A unifying theme of the course
    is the symmetry group of the regular icosahedron, whose elements can be
    realized as permutations, as linear transformations of vector spaces
    over finite fields, as collineations of a finite plane, or as vertices
    of a graph. Taught in a seminar format, and students will gain
    experience in presenting proofs at the blackboard.
