Xi, Ping Corrigendum to: “Sign changes of Kloosterman sums with almost prime moduli. II”. (English) Zbl 1479.11136 Int. Math. Res. Not. 2022, No. 1, 556-574 (2022). Summary: We give a corrigendum to our previous paper [ibid. 2018, No. 4, 1200–1227 (2018; Zbl 1406.11075)] and recover the same quantitative statement: the Kloosterman sum changes sign infinitely often as the modulus runs over squarefree numbers with at most seven prime factors.
