Anyon fusion matrix
= Anyon fusion matrix
{title2=$(N_b)_{ac}=N^c_{ab}$}
A <matrix> encoding multiplication by charge $b$ in the <anyon fusion rule>. These <matrices> commute in a <braided monoidal category>. On a <sphere>, the <dimension> of the <anyon fusion space> with puncture charges $a_1,\ldots,a_n$ and total <vacuum anyon> charge is $(N_{a_1}\cdots N_{a_n})_{11}$.
