Repdigits in Euler functions of Pell and associated pell numbers

Number Theory 2018-02-16 v1

Abstract

A natural number nn is called a repdigit if all its digits are same. In this paper, we prove that Euler totient function of no Pell number is a repdigit with at least two digits. This study is also extended to certain subclass of associated Pell numbers.
