algunas propiedades de los espacios de Banach pueden obtenerse a partir del estudio de los subespacios bidimensionales; en particular se estudian algunas caracterizaciones de espacios de Hilbert, uni-formemente convexos, estrictamente convexos y lisos. Aśı mismo se muestra cómo obtener información de la estructura normal en un espacio de Banach partiendo de sus subespacios bidimensionales. Abstract. In this article we explain how some properties of Ba-nach’s spaces can be obtained from the study of the two-dimensional subspaces; especially we studied some characterizations of Hilbert’s spaces, uniformly convex, strictly convex and smooth spaces. We also show how to obtain information of the normal structure of a Banach’s space from its t...
