    Operads, Lie algebras, and deformations.

    Friday 3rd September, 12-1pm, Carslaw 375.

    I shall explain what an operad is, and give some examples. Then I shall outline how the deformations of an algebraic structure can be described by a differential graded algebra, and how operads have been used recently by Beilinson-Ginzburg and Kontsevich to make the description more explicit and useful in some particular applications.
