Daily Reel
Name says it all.
Day 1 (Monday)
Basic definitions: group/subgroup, abelian/nonabelian.
Examples: ((Z/NZ), +), (M_2(R), +), ((Z/2Z) x (Z/2Z), +), ((Z/NZ)^x, *)
Order of a group. Order of an element in a group.
Think about how to prove two groups are "the same": (Z/4Z) and (Z/2Z) x (Z/2Z) are different. But ((Z/2Z), +) and ((Z/3Z)^x, *) are the same. Why?
Day 2 (Wednesday)
Definition of isomorphism/homomorphism.
"Deep analysis" of dihedral groups.
Start of discussion on symmetric groups.
Day 3 (Friday)
Deeper discussion of symmetric groups. Transpositions/disjoint-cycles
Basics about groups (think axiomatic-level proofs).
Day 4 (Wednesday)
Matrix groups: GL_n(F), SL_n(F)
Homomorphisms: in particular, the determinant map
Kernel of a homomorphism.
