Lecture
Graded Ring Structure on Cohomology
Description
This lecture discusses the graded ring structure on cohomology, focusing on the associativity and commutativity of the cup product. The instructor explains the proof of the associative property and the graded commutativity, emphasizing the use of free ZG-resolution. The lecture concludes with the application of these concepts in the context of H*(Q8; Z), showcasing a class and an isomorphism for isomorphic morphisms.
