Abstract: 

This is a continuation of the seminar talk from the previous week. The mod p cohomology of a space is an algebra over the Steenrod algebra A of cohomology operations, containing much additional information. So too are the Dickson algebras of polynomial invariants under the natural action of the general linear groups. We ask what the global structure of these A-algebras is, and will answer the question for p=2 by discovering an attractive description of minimal A-algebra generators and relations for the Dickson algebras.
