Norming C*-Algebras by C*-Subalgebras

Roger R. Smith, Texas A & M University

In this talk we will discuss the concept of one C*-algebra norming another C*-algebra. We will relate this to the question of when bounded maps are automatically completely bounded, and give various examples of this phenomenon. We will then give applications of these ideas to two problems in operator algebras: the bounded projection problem, and the vanishing cohomology problem. Very little background will be assumed, and the talk will be at an introductory level.
