Abstract. The aim of this paper is to study skew Poincaré-Birkhoff-Witt extensions of Baer, quasi-Baer, p.p. and p.q.-Baer rings. Using a notion of rigidness, we prove that these properties are stable over this kind of extensions.

Keywords: Baer, quasi-Baer, p.p. and p.q.-Baer rings, skew Poincaré- Birkhoff-Witt extensions.

Extensiones PBW torcidas de anillos de Baer,
quasi-Baer, p.p. y p.q-Baer

Resumen. El propósito de este artículo es estudiar las extensiones torcidas de Poincaré-Birkhoff-Witt de anillos de Baer, quasi-Baer, p.p. y p.q.-Baer. Utilizando una noción de rigidez, probamos que estas propiedades son estables para esta clase de extensiones.

Palabras clave: Anillos Baer, quasi-Baer, p.p, p.q.-Baer, extensiones torcidas de Poincaré-Birkhoff-Witt.
