Demonstrates how harmonic analysis can provide penetrating insights into deep aspects of modern analysis. This book presents an introduction to the subject as a whole and an overview of those branches of harmonic analysis that are relevant to the Kakeya conjecture.
Based on lectures presented by Popa at the NSF-CBMS Regional Conference held in Eugene, Oregon, in August 1993, this title offers a unified and self-contained presentation of the results presented in Popa's earlier papers.
