invariance of eigenvalues


Suppose M is a n×n matrix. In the following propositionPlanetmathPlanetmathPlanetmath when we say that “two matrices have the same spectra” we mean that the eigenvaluesMathworldPlanetmathPlanetmathPlanetmathPlanetmath coincide including multiplicity.

  1. 1.

    If S is an invertible matrix, then M and S-1MS have the same spectra.
