Orthogonal polynomials in the normal matrix model

I will discuss a new kind of orthogonality for polynomials that replaces the orthogonality with respect to
certain weights on the complex plane that appears in the normal matrix model. The orthogonal polynomials
have their zeros on curves in the complex planes, which I will describe in the simplest case of a cubic
potential.
