Density Bounds in Hua's Theorem for Prime Squares

Michael T. Lacey, Hamed Mousavi, Yaghoub Rahimi +1

We prove a density version of Hua's theorem in the five-variable case: if $P$ is a subset of the primes with relative lower density greater than $0.82$ , then every suffici…

Primes with Restricted-Digit Differences

Rui Han, Yaghoub Rahimi, Fan Yang

Fix a base $b \geq 2$ and a digit set $D \subset {0, 1, \dots, b - 1}$ , and let $C_{k}$ be the set of integers in $[0, b^{k})$ whose $k$ base- $b$ digits all lie in $\mathcal…

On the small denominator problem for generalized Minkowski--Funk transforms

Rui Han, Yaghoub Rahimi

Rubin's generalized Minkowski--Funk transforms $M_{t}^{α}$ on the sphere $S^{n}$ give rise, for irrational radii $t = cos (β π)$ , to a small denominator problem governed by the asy…
