Fourier transform of nonlinear images of self-similar measures: qualitative aspects
Amlan Banaji, Han Yu
The goal of this paper is to establish polynomial Fourier decay for images of self-similar measures on under sufficiently nonlinear real-analytic maps $f \colon…

Self-similar and self-conformal measures with slow Fourier decay
Simon Baker, Amlan Banaji
Given any function satisfying , we prove the existence of i) self-similar measures and ii) nonlinear self-conf…
