| Jun 9, 2012 at 2:42 | comment | added | Hugo Chapdelaine | @David, here I really mean isomorphic. Equal would be "easy" since one may compute the relation ideal for $B$ and $C$ and then test for equality. | |
| Jun 9, 2012 at 0:52 | comment | added | David E Speyer | Since $B$ and $C$ are both subalgebras of the same ring $A$, do you want to know whether they are isomorphic, or whether they are equal? | |
| Jun 9, 2012 at 0:06 | comment | added | MTS | I don't know much about algorithmic questions like this. But: it would probably help to specify whether you are given a set of generators for $B$ and $C$, or whether you merely have some implicit description of these subalgebras. | |
