Harmonic analysis and boundary value problems : selected papers from the 25th University of Arkansas spring lecture series, Recent progress in the study of harmonic measure from a geometric and analyt

These papers provide presentations of the problems that are at the forefront of harmonic analysis and partial differential equations. Topics include: the solution of the Kato conjecture, the two bricks problem, Cauchy integrals on non-smooth curves, and the Neumann problem for sub-Laplacians.
