Nonexistence of Frame Measures for Separated Uniform Consecutive-Digit Bernoulli Convolutions

Xiao-Ye Fu, Wei-Jie Wang

We investigate the existence problem of frame measures for uniform consecutive-digit Bernoulli convolutions under the separated scaling condition. Given parameters $N \geq 2$ and $0…

Turán problem on the union of three intervals of equal length

Xiao-Ye Fu, Yue-Kun Li, Wei-Jie Wang +1

This paper addresses the Turán extremal problem on the symmetric three-interval set $Ω_{λ} = (- 1, 1) \cup (λ - 1, λ + 1) \cup (- λ - 1, - λ + 1)$ , $λ \geq 0$ . We establish a discrete approximation…

A Walsh-Quotient Obstruction for Fourier Frames on Odd Reciprocal-Power Bernoulli Convolutions

Xiao-Ye Fu, Zi-Jian Song, Wei-Jie Wang

We introduce a Walsh--quotient obstruction to study Fourier-frame existence for symmetric two-branch Bernoulli convolutions \[ μ_{ρ,d} =\ast_{j=1}^{\infty} \frac12\bigl(δ_{-dρ^{j}/…
