Explores cohomology and the cross product, demonstrating its application in group actions like conjugation.
Covers the concept of group cohomology, focusing on chain complexes, cochain complexes, cup products, and group rings.
Explores the construction of group representations through various methods and provides an illustrative example using the standard representation of sr2 on c2.
Explores Wedderburn's theorem, group algebras, and Maschke's theorem in the context of finite dimensional simple algebras and their endomorphisms.
