| Jan 29, 2016 at 22:02 | comment | added | David Handelman | Any ring isomorphism between representation rings that sends irreducibles to irreducibles (and vice versa) is automatically an order isomorphism. So the OP's question is equivalent to the order isomorphism question. | |

| Jan 29, 2016 at 19:00 | comment | added | Xiao-Gang Wen | I assume that two fusion rings $N^{ij}_k$ and $\tilde N^{ij}_k$ are the same if $N^{ij}_k$ equal to $\tilde N^{ij}_k$ after some permutations of indices. | |
