Fractals and Spectra

Focusing on the interplay between fractal geometry and Fourier analysis, this book explores the spectral properties of fractal (pseudo)differential operators. It highlights recent advancements in function space theory that connect to fractal methods, particularly in spectral problems related to degenerate pseudodifferential operators. The text provides insights into entropy numbers and eigenvalue distribution, presenting new techniques not widely covered in existing literature. Additionally, it serves as a continuation of previous works in the field, enriching the understanding of fractal analysis.
