On the connectedness of the spectrum of forcing algebras
We study the connectedness property of the spectrum of forcing algebras over a noetherian ring. In particular we present for an integral base ring a geometric criterion for connectedness in terms of horizontal and vertical components of the forcing algebra. This criterion allows further simplificati...

En particular, presentamos un criterio de conexidad cuando el anillo base es un dominio en términos de las componentes verticales y horizontales del álgebra de forzado. Este criterio nos permite obtener simplificaciones en el caso en el que el anillo base es local, o 1--dimensional o un dominio de factorización única. Además, discutimos sobre si la conexidad de las álgebras de forzado es una propiedad local. Finalmente, presentamos una caracterización de pertenencia a la clausura entera de un ideal en términos de la conexidad universal del correspondiente morfismo de forzado.application/pdfspaUniversidad Nacuional de Colombia; Sociedad Colombiana de matemáticashttp://revistas.unal.edu.co/index.php/recolma/article/view/45192Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de MatemáticasRevista Colombiana de MatemáticasRevista Colombiana de Matemáticas; Vol. 48, núm. 1 (2014); 1-19 2357-4100 0034-7426Brenner, Holger and Gómez-Ramírez, Danny de Jesús (2014) On the connectedness of the spectrum of forcing algebras.

We study the connectedness property of the spectrum of forcing algebras over a noetherian ring. In particular we present for an integral base ring a geometric criterion for connectedness in terms of horizontal and vertical components of the forcing algebra. This criterion allows further simplifications when the base ring is local, or one--dimensional, or factorial. Besides, we discuss whether the connectedness of forcing algebras is a local property. Finally, we present a characterization of the integral closure of an ideal by means of the universal connectedness of the corresponding forcing morphism. |
