[401]  arXiv:2211.03585 (cross-list from physics.flu-dyn) [src]

Title: The Influence of Vortex Sheet Geometry on the Kelvin-Helmholtz Instability

Authors: Ryan Murray, Galen Wilcox

Comments: Regretfully, we have found a mistake that renders the main result (Theorem 2.2) incorrect. It is necessary to treat positive and negative Fourier modes separately in order to satisfy analyticity requirements when evaluating the integral (2.26). Proceeding through similar steps with negative modes, the matrix analogous to (2.31) has positive eigenvalues, implying instability
