Entanglement in a multiverse with no common space-time
Inter-universal entanglement may even exist in a multiverse in which there is
no common space-time among the universes. In particular, the entanglement
between the expanding and contracting branches of the universe might have
observable consequences in the dynamical and thermodynamical properties of one
single branch, making therefore testable the whole multiverse proposal, at
least in principle.Comment: 4 pages. Prepared for the proceedings of the Multiverse and

The best constant for the centered maximal operator on radial decreasing functions
We show that the lowest constant appearing in the weak type (1,1) inequality
satisfied by the centered Hardy-Littlewood maximal operator on radial
integrable functions is 1.Comment: corrected typo
