Abstract: © 2018 Society for Industrial and Applied Mathematics. There is unfortunately a small gap in the original proof of one of the theorems in "Suppression of BlowUp in PatlakKellerSegel Via Shear Flows" [Bedrossian and He, SIAM J. Math. Anal., 49(2017), pp. 47224766]. Specifically, the proof of Theorem 2(b), the case T x R2, has an error in Lemma 4.1, the control on the free energy. The application of Sard's theorem incorrectly ignores boundary contributions at infinity and we do not see a way to justify the stated inequality rigorously. The correction is not difficult but does require a slightly different approach to the problem of controlling the twodimensional free energy. Below we outline the corrected proof.
