A project on "Approximations of groups and modules" has been submitted to the DAAD as part of a PPP programme. Together with Professor Dr. Jose Rodriguez (University of Almeria, Spain) and Professor Dr. Sergio Estrada (University of Murcia, Spain) we are investigating properties of groups and moduels that are preserved (or not preserved) under cellular covers and envelopes as well as transitivity properties of structures. The project will last for two years with an intensive exchange between the researchers.
2010 - 2012: Supported by the DAAD we had a research project with Professor Dr. Rüdiger Göbel
(University of Duisburg-Essen) and Professor Dr. Jan Trlifaj (Charles University of Prague) on "Methods of Model Theory, Logic and Set Theory in the Structure Theory of Modules over
2008 - 2010: Supported by the German Research Foundation we had a project with Professor Dr. Rüdiger
Göbel (University of Duisburg-Essen) and Professor Dr. Ralf Schindler (University of Münster) on "The interplay between Algebra and Logic"
