DESCRIPTION:Title: Tutte and Bollobas-Riordan polynomials: coefficient meas
 ures and related problems.\n\nAbstract: We study the distribution of coeff
 icients of rank polynomials of random sparse graphs. We first discuss the 
 limiting distribution for general graph sequences that converge in the sen
 se of Benjamini-Schramm. Then we compute the limiting distribution and New
 ton polygons of the coefficients of the rank polynomial of random d-regula
 r graphs. We next consider related results for Bollobas-Riordan polynomial
 s associated to ribbon graphs. Finally\, we discuss some numerical results
  about zeros of those polynomials. This is joint work with L. Turner\, C. 
 MacRury\, S. Norin\, T. Langsetmo\, M. Medeiros Charbonneau and I. Rivin.
