A note on prime \(k\)-th power nonresidues
The autbhor shows that if \(p\) is a prime and \(n<c\log p/\log\log p\) then the \(n\)th least prime \(k\)th power nonresidue modulo \(p\) is \(O(p^{1/4+\varepsilon}\). \textit{K. K. Norton} has obtained a stronger result (see [Notices Am. Math. Soc. 21 (1974)]).
