Ill-posedness Results for Model Equations for Water Waves

The discussion will center around both deep and shallow water wave models. Certain naturally derived models are examined and shown to be ill-posed in Hadamard's classical sense. The ill-posedness does not stem from trying to work in very large function classes, but instead seems intrinsic to the models and obtains even in quite smooth function spaces.
