This note is to bring attention to one of the ending questions in Grothendieck's thesis [3, Chapter 2, p. 134]:
Is the space DLp isomorphic to s ⊗ Lp?
The problem has been, as we shall see, essentially solved by Valdivia and Vogt. This fact, however, seems to have remained unnoticed. Supports this belief of the authors the fact that they have been unable to find an explicit reference to its solution.
