Título: The Banach-Saks property of a set and its convex hull
Resumo: We present an example of a set which has the Banach-Saks property, yet its convex hull does not. In fact, our example has Banach-Saks rank 1 while its convex hull has rank 2. We will discuss the relationship between the ranks of a set and of its convex hull. This is a Joint work with C. Ruiz and P. Tradacete (Madrid).
