This book presents a curated selection of recent research in functional analysis and fixed-point theory, exploring their applications in interdisciplinary fields. The primary objective is to establish a connection between the latest developments in functional analysis and fixed-point theory and the broader interdisciplinary research landscape. By doing so, this book aims to address the needs of researchers and experts seeking to stay up-to-date with the cutting-edge research trends in functional analysis, fixed-point theory and related areas. It also aims to pave the way for applying functional analysis and fixed-point theory to solve interdisciplinary problems in various domains, including but not limited to fractional calculus, integral equations, queuing theory, convex analysis, harmonic analysis and wavelet analysis.

Collects select chapters on functional analysis and fixed-point theory and their interdisciplinary applications Discusses theoretical and application-oriented cutting-edge research in functional analysis and fixed-point theory Introduces topics on spectrum continuity, best proximity point, infinite programming, and Kohlenbach hyperbolic spaces
