Higher random indestructibility of MAD families

Abstract

We give a combinatorial characterization of when a maximal almost disjoint family of a weakly compact cardinal κ\kappa is indestructible by the higher random forcing Qκ\mathbb Q_\kappa. We then use this characterisation to show that add(nullκ)=bκ=cκ\mathrm{add}(\mathbf{null}_\kappa) = \mathfrak b_\kappa = \mathfrak c_\kappa implies the existence Qκ\mathbb Q_\kappa-indestructible family. The results and proofs presented here are parallel to those for classical random forcing.
