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

Rui Han, Yaghoub Rahimi

Rubin's generalized Minkowski--Funk transforms $M_{t}^{I^} \pm$ on the sphere $S^{n}$ give rise, for irrational radii $t = cos (I^^{2} I ¨ )$ , to a small denominator problem governed by the…

A Density Theorem for Higher Order Sums of Prime Numbers

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

Let $P$ be a subset of the primes of lower density strictly larger than $\frac{1}{2}$ . Then, every sufficiently large even integer is a sum of four primes from the set $P$ . We establis…
