From the reviews:  "This volume is based on lectures delivered at the International Conference ''New trends in Harmonic and Complex Analysis'', held May 7-12, 2007 . . results presented in this volume trace further developments of frontier research exploring the bridge between complex real analysis potential theory partial differential equations and modern topics of fluid mechanics and mathematical physics. The present volume will be of interest for specialists and graduate students in mathematics and mathematical physics. Many papers in this volume are surveys whereas others represent original research." (L''Enseignement Mathématique, Vol. 56 (2), 2010)
