Title: Measure rigidity and p-adic Littlewood-type problems
Abstract: A drama in four acts, loosely based on my new paper with Manfred Einsiedler. Brief synopsis: Recent developments in measure rigidity of higher rank actions due to Lindenstrauss and Einsiedler-Katok-Lindenstrauss give rise to new results and conjectures in so-called multiplicative Diophantine approximation over the product of real and p-adic fields.
