Some of them deal with specific applications\nof optimal control, such as phase field models, obstacle problems, Stokes problems, or wave form\ninversion. Other talks are devoted to aspects of non-smoothness or to special types of controls, e.g.\nfunctions of bounded variation, bang-bang controls, or Dirichlet boundary controls. Another part of\nthe contributions discusses numerical methods, namely error estimates or the converges of semismooth\nNewton methods. Moreover, specific difficulties are considered that are due to non-coercive problems\nor the numerics in non-convex spatial domains. The minisymposium will confirm ongoing progress in\nthe numerical analysis of PDE control.<br>\n\n<strong>Mini symposium organizers:<\/strong><br>\nArnd R\u00f6sch (Universit\u00e4t Duisburg-Essen)<br>\nFredi Tr\u00f6ltzsch (Technische Universit\u00e4t Berlin)<br>\n<\/p>\n<p>\n<strong>Session 3.
