Corrigendum to “The conjecture of Ulam on the invariance of measure on Hilbert cube” [J. Math. Anal. Appl. 481 (2) (2020) 123500]

Abstract Theorem 2.2 in the original paper [1] is incorrectly stated. Indeed, Theorem 2.2 is essential to proving Theorem 3.1 that is one of the main results in [1] . In this corrigendum, we will outline the processes of correcting Theorem 2.2 in [1] and proving Theorem 3.1 in [1] using the modified Theorem 2.2.
