GIVEN PROBLEM: Let φ: G --> H be an isomorphism between groups G and H and let S be a subgroup of G. Prove that φ(S) is a subgroup of H. notation: φ(S) = {h∈H: φ(x)=h for some x∈G} My Solution: So by the subgroup thrm., we need to show that φ(S) has an identity, inverses, and closure. 1. First we need to show that the identity of H is in φ(S) Let h = eh for all h∈H Then φ(eg) = eh So the identity of H is in φ(S) . 2. Next we need to show that if a∈φ(S), then a-1∈φ(S) No clue how to prove this, help? 3. Lastly, we must show that if a,b∈φ(S), then ab∈φ(S) I think I know the answer. Its a chip on Duckys shoulder. OK you > Me. Awesome. now seriously, someone figure that out for me, and I owe em for life. That proof is 8% of my grade and I cant figure it out. |
