作者描述了一个算法,用于构造一个良好的多项式基的相对不变量与任何真实的表示的晶体学点群(CPG)。这里的新奇在于算法的通用性。它依赖于这样一个事实,即一个典型的真实的表示的CPG有一个特别简单的形式,并有一个密切的关系,少数低维矩阵群的不变量是已知的,表现良好。
The authors describe an algorithm for constructing a good polynomial basis for the relative invariants associated with any real representation of a crystallographic point group (CPG). The novelty here is the universality of the algorithm. It depends on the fact that a typical real representation of a CPG has a particularly simple form and has a close relationship to a small number of low-dimensional matrix groups whose invariants are known and well behaved.
