DESCRIPTION:Speaker: David Renfrew\nhosted by Laszlo Erdös / Andrew Campbe
 ll\nAbstract: We consider the density of states of structured Hermitian an
 d non-Hermitian random matrices with a variance profile. As the dimension 
 tends to infinity the associated eigenvalue density can develop a singular
 ity at the origin. The severity of this singularity depends on the relativ
 e positions of the zero submatrices. We provide a classification of all po
 ssible singularities and determine the exponent in the density blow-up.
