... The discrete analogue of a “nodal domain” is a connected set of vertices, i.e., a connected subgraph of a graph G, on which the eigenvector has the same, strict or loose, sign. Of course, such a set of vertices is not ... Lihat dokumen lengkap

... A straightforward computation reveals that B + tX commutes with C for all t ∈ F. Moreover for t = 0, the matrix B + tX has more than one point in the its spectrum. So, by Lemma 2.4, the triple (A, B + tX, C) belongs to ... Lihat dokumen lengkap
