This book represents the proceedings of the international conference on complex and harmonic analysis, which was held in May 2006 at the Aristotle University of Thessaloniki. The volume contains 23 articles from a broad range of topics including geometric function theory, complex iteration, function spaces, composition operators, extremal problems, potential theory, maximal functions, analysis on manifolds and others. The conference was dedicated to the memory of Nikos Danikas (a member of Thessaloniki University) who died in 2004. The introductory paper on the mathematical work of Nikos Danikas is written by W.K. Hayman and it is followed by an article on Danikas measures written by V. Nestoridis. The book can be recommended to students and researchers in the area.
