Title: Abstract Algebra. Automorphism groups • Abstract: An automorphism is an isomorphism from a group G to itself. If G is a group, then the collection Aut(G) of automorphisms of G is itself a group (under function composition). The automorphism group of Z/nZ is isomorphic to U(n), the group of units modulo n under multiplication. • This video accompanies page 58 of the class notes (https://www.math.colostate.edu/~adams...) for an Introduction to Abstract Algebra class (https://www.math.colostate.edu/~adams...)
