Chapter 1 Some results related with n−variables non conformable fractional derivatives -- Chapter 2 On The Spectral Continuity Of The Essential Spectrum -- Chapter 3 Infinite programming and application in the best proximity point theory -- Chapter 4 Some fixed point results for the modified iteration process in hyperbolic spaces with an application -- Chapter 5 On common fixed point results for integral type contractive conditions in S-metric spaces and application to integral equations -- Chapter 6 On ( f ,λ)− Harmonic Summability.

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.
