论文摘要
我们表征了在动力学系统的性质方面，表征了半体体产物的自由基。我们表明，当且仅当在闭合复发点的闭合而消失的傅立叶系数而较大的X的最大完美子集中消失时，且仅当消失的傅立叶系数消失时，且只有在最大的X上消失时，我们就表明了半分解产物的元素a。
We characterize the hypocompact radical of a semicrossed product in terms of properties of the dynamical system. We show that an element A of a semicrossed product is in the hypocompact radical if and only if the Fourier coefficients of A vanish on the closure of the recurrent points and the 0-Fourier coefficient vanishes also on the largest perfect subset of X.
