Corrigendum to “Dynamical Gröbner bases” [J. Algebra 301 (2) (2006) 447–458] and to “Dynamical Gröbner bases over Dedekind rings” [J. Algebra 324 (1) (2010) 12–24]

In this corrigendum, I correct a mild error in a technical lemma of Yengui (2006) [5], . This error affected some results and examples in Hadj Kacem and Yengui (2010) [3], and Yengui (2006) [5].
