| Ok, we know A and B are homomorphic, now you want to see that the kernel of A is isomorphic to to this non trivial subgroup of B... | |
 | |  |
|
 |
| | |
| Well, the definition of kernel is it is the set of elements mapped to the identity of the other set | |
| | |

| | |
| Well, ok erase the last 8 lines... what I meant was that the extended union of all A in gamma shows that x is in both A and B.... | |
| | |
|
 |
| | |
| But unions in set theory correspond to "or" statements in logic.... | |
| | |

| Ok, well, class dismissed for now then.... I need to go talk to Dr. Seaman about.... something.... | |
