Harmonic Analysis and Boundary Value Problems

This volume presents research and expository articles by the participants of the 25th Arkansas Spring Lecture Series on 'Recent Progress in the Study of Harmonic Measure from a Geometric and Analytic Point of View' held at the University of Arkansas (Fayetteville). Papers in this volume provide clear and concise presentations of many problems that are at the forefront of harmonic analysis and partial differential equations. The following topics are featured: the solution of the Kato conjecture, the 'two bricks' problem, new results on Cauchy integrals on non-smooth curves, the Neumann problem for sub-Laplacians, and a new general approach to both divergence and nondivergence second order parabolic equations based on growth theorems. The articles in this volume offer both students and researchers a comprehensive volume of current results in the field.
