Title: Amalgamation of measures and Banach lattices

Abstract: Given two measures that coincide on the intersection of their domains, can we find a measure that is a common extension of those two? Kellerer's results on marginal measures constitute an important partial positive answer. We will see how this is connected to some basic properties of the category of Banach lattices, like amalgamation and existence of injective objects. Joint work with Pedro Tradacete.

Title: Boolean algebras obtained by push-out iteration

Abstract. We discuss the notion of push-out in the category of Boolean algebras, and we describe a method of constructing Boolean algebras by transfinite iterative push-outs. Under CH and in a model obtained by adding \(\aleph_2\) Cohen reals to a model of CH, \(P(\omega)/fin\) is such an algebra.
