Let G and H be groups and : H Aut Ga homomorphism. Let G X
Question:
Let G and H be groups and θ : H → Aut Ga homomorphism. Let G Xθ H be the set G X H with the following binary operation: (g,h)(g',h') = (g[θ(h)(g')],hh'). Show that G Xθ H is a group with identity element (e,e) and (g,h)-1 = (θ(h-1)(g-1),h-1). G Xθ H is called the semidirect product of G and H.
