Products of Conjugacy Classes in $SU(2)$

[摘要] We obtain a complete description of the conjugacy classes$C_1,dots,C_n$ in $SU(2)$ with the property that $C_1cdotsC_n=SU(2)$. The basic instrument is a characterization of theconjugacy classes $C_1,dots,C_{n+1}$ in $SU(2)$ with $C_1cdotsC_{n+1}i I$, which generalizes a result of cite{Je-We}.
