Quadratic non-residues and non-primitive roots satisfying a coprimality condition
Let be any integer and let be a given real number. In this short note, we prove that for all
primes satisfying p\equiv 1\pmod{q}, \quad \log\log p > \frac{\log
6.83}{\frac{1}{2}-\epsilon} \mbox{ and } \frac{\phi(p-1)}{p-1} \leq \frac{1}{2}
- \epsilon, there exists a quadratic non-residue which is not a
primitive root modulo such that .Comment: to appear in Bulletin of the Australian Mathematical Societ
Set Equidistribution of subsets of (Z/nZ) *
In 2010, Murty and Thangadurai [MuTh10] provided a criterion for the set equidistribution of residue classes of subgroups in (Z/nZ) *. In this article, using similar methods, we study set equidistribution for some class of subsets of (Z/nZ) *. In particular, we study the set equidistribution modulo 1 of cosets, complement of subgroups of the cyclic group (Z/nZ) * and the subset of elements of fixed order, whenever the size of the subset is sufficiently large
