ABSTRACT. We provide a self-contained and constructive approach to reduce a self-adjoint linear transformation defined on a pseudo-unitary (resp., pseudo- euclidean) space to a canonical form.
Keywords and phrases. Pseudo-unitary, pseudo-euclidean, self-adjoint, orthogonal.
2000 Mathematics Subject Classification. Primary: 15A21. Secondary: 15A57.
RESUMEN. Nosotros damos una aproximación auto-contenida y constructiva para reducir una transformación lineal auto-adjunta definida sobre un espacio pseudo-unitario (resp. pseudo-euclidiano) a una forma canónica.
