where \(\mathrm {d}^{3}x\)  denotes the Lebesgue measure on \(\mathfrak {su}(2)\cong \mathbb {R}^{3}\)  and where the star product has to be understood as \(\hat{\varphi }(x_{i})\star \hat{\varphi }(x_{i}):=(\hat{\varphi }\star \hat{\varphi }_{-})(x_{i})\)  for repeated arguments with \(\hat{\varphi }_{-}(x_{i}):=\hat{\varphi }(-x_{i})\) . More details can be found in the original article [1]} as well as in [2]}.

где \(\mathrm {d}^{3}x\) обозначает меру Лебега на \(\mathfrak {su}(2)\cong \mathbb {R}^{3}\), а звездная операция должна трактоваться как \(\hat{\varphi }(x_{i})\star \hat{\varphi }(x_{i}):=(\hat{\varphi }\star \hat{\varphi }_{-})(x_{i})\) для повторяющихся аргументов с \(\hat{\varphi }_{-}(x_{i}):=\hat{\varphi }(-x_{i})\). Более подробную информацию можно найти в оригинальной статье [1] и в [2].
