Isospectral
Isospectral In mathematics, two linear operators are called isospectral if they have the same spectrum. Roughly ... complex square matrices, the relation of being isospectral for two diagonalizable matrices is just similarity ... the concept, since we can have an isospectral family of matrices of shape A(t ...
