Trinomials, singular moduli and Riffaut's conjecture

Number Theory 2021-08-30 v2

Abstract

Riffaut (2019) conjectured that a singular modulus of degree h3h\ge 3 cannot be a root of a trinomial with rational coefficients. We show that this conjecture follows from the GRH, and obtain partial unconditional results.
