On the $p$-adic valuations of values of Legendre polynomials

Number Theory 2025-05-15 v1

Abstract

We prove an explicit formula for the pp-adic valuation of the Legendre polynomials Pn(x)P_n(x) evaluated at a prime pp, and generalize an old conjecture of the third author. We also solve a problem proposed by Cigler in 2017.
