N. N. Namboodiri -- On the asymptotic eigenvalue distribution of matrices -- Singular value decomposition of unbounded absolutely minimum attaining operators -- A note on eigenvalues and singular values of variable Toeplitz matrices and matrix-sequences, with application to variable two-step BDF approximations to parabolic equations -- Operators in the Fock-Toeplitz algebra -- Wavelets on the interval: a short survey -- A survey of collectively compact sets of operators and compact operator version of Nayak’s theorem -- Survey on the convexity of the Berezin range -- Novel fractional wavelet frame -- On multilinear extensions of mid p-summing operators.This book is a collection of recent developments in spectral and approximation theory. The results collected here were presented at the International Conference on Spectral and Approximation Theory (ICSAT-2023) which took place at Cochin University of Science and Technology in Kerala, India. The conference ICSAT-2023 focuses on two significant areas in mathematics: spectral theory and approximation theory.Trends in Mathematics,2297-024XOperator theoryFunctional analysisApproximation theoryOperator TheoryFunctional AnalysisApproximations and ExpansionsOperator theory.Functional analysis.Approximation theory.Operator Theory.Functional Analysis.Approximations and Expansions.515.724Asharaf Noufal1836748Bauer Wolfram234339Bhat B.
