Covers the concept of Steenrod Squares and their applications in stable cohomology operations.
Covers the concept of group cohomology, focusing on chain complexes, cochain complexes, cup products, and group rings.
Explores cohomology and the cross product, demonstrating its application in group actions like conjugation.
Explores fundamental groups, homotopy classes, and coverings in connected manifolds.
Explores the CW Approximation Theorem, constructing CW complexes from spaces to ensure isomorphism on homology groups.
Covers fibrant objects, lift of horns, and the adjunction between quasi-categories and Kan complexes, as well as the generalization of categories and Kan complexes.
