Correction to: On elliptic systems in \({\mathbb{R}}^ n\)
This note is to announce an error in the statement (and proof) of Theorem 4 in [ibid. 150, 125-135 (1983; Zbl 0517.35031)], namely the equality of the Fredholm index of the variable coefficient elliptic system A and the constant coefficient elliptic system is false.
