Title: Necessary Conditions for Two Weight Weak Type Norm Inequalities for Multilinear Singular Integral Operators

Abstract: In this talk we will discuss necessary conditions for a multilinear singular operator T to satisfy two weight weak type norm inequalities provided the kernel of T satisfies a weak non degeneracy condition. As an application of our techniques we will show that in general a multilinear singular integral does not satisfy a two weight strong endpoint estimate.
