Abstract:
The vector space with basis the planar binary trees can be equipped with a Hopf algebra structure, which is neither commutative nor cocommutative. This structure turns up in at least 3 different areas of mathematics: algebra (operads), algebraic topology (cellular decompositions of the sphere), and mathematical physics (Schwinger equation).Date: Wednesday, November 3, 1999
