Title: Norm inflation for the 2D Debye-Hu ̈ckel system in Besov Spaces Computational and Applied Mathematics Colloquium Chao Deng, University of Colorado at Boulder http:// Based on the construction of Bourgain and Pavlovi\'{c} {\it JFA {\bf 255}(2008):\! 2233--2247}" for the Navier-Stokes equations in periodic case, we demonstrate that the solutions to the Cauchy problem for the two dimensional Debye-H\"uckel system can develop norm inflations in with data in $B^{-\frac{3}{2}}_{4,\infty}(R^2)$.
