分析了多通道弹性散射体的乘性传递矩阵M在正交、酉性和辛性情况下的空间结构。我们用一组径向参数和两个辅助酉阵来参数化这个空间，径向参数与弹性散射体的电导简单相关，它们的结构取决于普适性类。
We analyze for the orthogonal, unitary and symplectic cases the structure of the space where the multiplicative transfer matrix M of a multi-channel elastic scatterer is defined. We parametrize this space with a set of radial parameters, which are related in a simple way to the conductance of the elastic scatterer, and with two auxiliary unitary matrices, whose structure depends on the universality class.
