In this corrigendum, we offer a correction to [J. Korean. Math. Soc., 54 (2017), pp. 461–477]. We construct a counterexample for the strengthened Cauchy–Schwarz inequality used in the original paper. In addition, we provide a new proof for Lemma 5 of the original paper, an estimate for the extremal eigenvalues of the standard unpreconditioned FETI-DP dual operator.
