Abstract
What follows is a slightly expanded and updated version of lectures I gave in May 2011 during a workshop on “Group actions, generalized cohomology theories and affine algebraic geometry” at the University of Ottawa. Among the participants were young beginning mathematicians as well as seasoned experts in diverse aspects of algebra and geometry. The aim (by order of the organizers) was to give all of them a taste of “cancellation for affine algebraic varieties.”As much as possible I have tried in these notes to maintain the informal style of the lectures. They are a very selective and far from an exhaustive treatment of the subject. Should the reader note a tendency to frequently switch between the algebraic and geometric point of view: this is by design.
