Control of Some Coupled Pde Systems of Mixed TypesThe initial part of the talk reviews some results on control and stabilization of some coupled PDE systems of mixed types, obtained with our collaborators. The latter part is specifically on new results with our collaborators, on stabilization or the lack of, for these systems. An outline of the proof for both positive and negative results will be indicated. These do not use the full knowledge of the spectrum. The negative result relies on a construction of highly localized solutions using certain ansatz involving complex exponentials and hence works for such coupled systems with variable coefficients and lower order terms.Uploaded 07-10-26 Learn more about your ad choices.
