Resumen de Tensor stable Fréchet and (DF)-spaces

J. Bonet, Juan Carlos Díaz Alcaide , Jari Taskinen

• In this paper we introduce and investigate classes of Fréchet and (DF)-spaces which constitute a very general frame in which the problem of topologies of Grothendieck and some related dual questions have a positive answer. Many examples of spaces in theses classes are provided, in particular spaces of sequences and functions. New counterexamples to the problems of Grothendieck are given.
