On the Scaled Inverse of $(x^{i} - x^{j})$ modulo Cyclotomic Polynomial of the form $Φ_{p^{s}} (x)$ or $Φ_{p^{s} q^{t}} (x)$

Jung Hee Cheon, Dongwoo Kim, Duhyeong Kim +1

The scaled inverse of a nonzero element $a (x) \in Z [x] / f (x)$ , where $f (x)$ is an irreducible polynomial over $Z$ , is the element $b (x) \in Z [x] / f (x)$ such…
