Remark on a paper of Stux concerning squarefree numbers in non-linear sequences
Georg Johann Rieger · Pacific Journal of Mathematics · 1978
Stux studied squarefree numbers of the form [fin)]; his most interesting application is f(n)=n c for real c with Kc< 4/3.We would like to point out that a stronger result follows immediately from estimates of Deshouillers.
