On Discriminator Problems Involving Powers Of5

Let f(x)∈[x]with f(1)<f(2)<f(3)<…. For any positive integer n, the discriminator Df(n) is the smallest positive integer m such that f(1),f(2),f(3),… f(n) are pairwise distinct modulo m. There are lots of research work on discriminator of poly-nomials. In this thesis, for f(x)=x(5x+2) we show that...
