Mad spectra
The mad spectrum is the set of all cardinalities of infinite maximal almost disjoint families on ω. We treat the problem to characterize those sets A which, in some forcing extension of the universe, can be the mad spectrum. We give a complete solution to this problem under the assumption θ = θ, where θ = min(A). §0. Introduction. Recall that A ⊆ [ω] is called almost disjoint (a. d. for short),...
متن کاملMAD families and the rationals
Rational numbers are used to classify maximal almost disjoint (MAD) families of subsets of the integers. Combinatorial characterization of indestructibility of MAD families by the likes of Cohen, Miller and Sacks forcings are presented. Using these it is shown that Sacks indestructible MAD family exists in ZFC and that b = c implies that there is a Cohen indestructible MAD family. It follows th...

Text by Mitch Leslie [email protected] Brief encounter A t fi rst glance, some of the cell’s communication proteins seem ill-suited for the job. They are embedded in the outer layer of the plasma membrane and have no direct connection to the cell interior. Yet they manage to relay signals across the membrane. The proteins tend to congregate, and on page 169, Chen et al. show that this gre...

متن کاملVery Mad Families
The notion of very mad family is a strengthening of the notion of mad family of functions. Here we show existence of very mad families in different contexts.
