Title: Character Sums Over Shifted Primes

Abstract: For integer $q$, let $\chi$ be a primitive character of 
the multiplicative group $\left(\mathbb{Z}/q\mathbb{Z}\right)^{*}$. 
For any integer $a$ coprime to $q$, we consider bounding the sums 
$\sum_{p\le N}\chi(p+a)$ where the above sum is over all prime 
numbers less than $N$. We show cancellation in such sum occurs in 
the range $N\ge q^{5/6+\varepsilon}$ which improves a result of 
Friedlander, Gong and Shparlinski.
