Sergey Zelik visited the Centre for Mathematical Sciences at the University of Cambridge today (2 November) and gave a talk in the Applied and Computational Analysis Seminar Series. The title of his talk was “Nonlinear localization and regularity of solutions of Brinkman-Forchheimer type equations.” In the talk, he discussed the regularity of Navier-Equations in 3D with Forchheimer nonlinearities including the case of slightly compressible equations. The main emphasis was on the case of Dirichlet boundary conditions and fast growing nonlinearities. Some results about the long-time behaviour of the corresponding solutions were also stated. His host for the visit was Edriss Titi. The photo below shows Sergey before the talk meeting up in the Maths Cafe with two ex-Surrey students (Anusha Schutz and Jeffrey Thompson) who are now students on the Part III course at Cambridge.
