We consider tridiagonal matrices (aij)i,j=1n with constant main diagonal and such that ai,i+1ai+1,i=1 for i=1,…,n−1. For these matrices, criteria are established under which their Kippenhahn curves...

具有包含椭圆分量的 Kippenhahn 曲线的倒数矩阵的统一方法



我们认为三对角矩阵 (aij)i,j=1n 具有恒定的主对角线,因此 ai,i+1ai+1,i=1 对于 i=1,...,n−1。对于这些矩阵,建立了它们的 Kippenhahn 曲线的标准......
