Weba Perron{Frobenius matrix Awith h(f) = logˆ(A), whose eigenvalues come in reciprocal pairs. Theorem 1.1 may therefore be useful for bounding h(f) from below, if the complexity of the train track and hence the rank of A can be controlled. The Perron polynomial of a directed graph enjoys many similarities with WebThe primitive case is the heart of the Perron-Frobenius theory and its applica-tions. There are various proofs. See the final remarks for acknowledgments on this one. The spectral radius of a square matrix is the maximum of the moduli of its eigenvalues.

Web也就是说，一个矩阵的秩越大，它的像空间的维数就越大。. 如果一个线性变换作用在一个向量上，只改变了它的长度不改变它的方向，那这个向量就是这个线性变换的特征向量，而长度改变的比例就是特征值。. 所以矩阵特征值（特征向量）的个数（即特征空间 ...
