This comprehensive book explores the intricate realm of fine potential theory. Delving into the real theory, it navigates through harmonic and subharmonic functions, addressing the famed Dirichlet problem within finely open sets of . These sets are defined relative to the coarsest topology on , ensuring the continuity of all subharmonic functions. This theory underwent extensive scrutiny starting from the 1970s, particularly by Fuglede, within the classical or axiomatic framework of harmonic functions. The use of methods from fine potential theory has led to solutions of important classical problems and has allowed the discovery of elegant results for extension of classical holomorphic function to wider classes of “domains”. Moreover, this book extends its reach to the notion of plurisubharmonic and holomorphic functions within plurifinely open sets of  and its applications to pluripotential theory. These open sets are defined by coarsest topology that renders all plurisubharmonic functions continuous on . 

The presentation is meticulously crafted to be largely self-contained, ensuring accessibility for readers at various levels of familiarity with the subject matter. Whether delving into the fundamentals or seeking advanced insights, this book is an indispensable reference for anyone intrigued by potential theory and its myriad applications. Organized into five chapters, the first four unravel the intricacies of fine potential theory, while the fifth chapter delves into plurifine pluripotential theory.

Über Autor(innen)

Mohamed El Kadiri is formerly a Professor of Mathematics in Mohammed 5 University in Rabat. Morocco, for more than 35 years. His research activities include classical, axiomatic and probabilistic potential theories, complex variables theory, Choquet’s theory and biharmonic functions theory. He collaborated with Bent Fuglede in a series of works on the Martin boundary of a fine domain in and relative questions: integral representation of nonnegative finely harmonic functions. In his collaboration with Fuglede and with Wiegerinck on the theory of plurifinely plurisubharmonic functions, he contributed to establishing the most important properties of the latter class of functions, and to the extension of the Monge-Ampère operator for finite function in this class and to the study of maximal plurifinely plurisubharmonic functions.

Bent Fuglede is formerly Professor Emeritus at the Department of Mathematical Sciences, University of Copenhagen, Denmark. His research fields include functional analysis, potential theory, classical and axiomatic potential theories, capacity theory, fine topology, finely harmonic functions, Dirichlet problem, maximum principles and complex analysis in one or more variables. Author of two books,  and  his works greatly influenced the development of potential theory during the second half of the 20th century.
