Computability in Europe 2009 (CiE 2009) is organised by the research group in Mathematical Logic and Theoretical Computer Science at the Department of Mathematics and Computer Science of the Ruprecht-Karls-Universität Heidelberg and takes place in Heidelberg, Germany, 19 - 24 July 2009.

CiE 2009 is the fifth conference in a newly evolving conference series under the heading Computability in Europe, which started 2005 in Amsterdam as
CiE 2005: New Computational Paradigms and has been very successfully continued in Swansea CiE 2006: Logical Approaches to Computational BarriersSiena CiE 2007: Computation and Logic in the Real Worldand Athens CiE 2008: Logic and Theory of Algorithms.

The scope of CiE 2009 encompasses theoretical and practical issues in computer science, with a focus on the interplay between these types of issues. In particular submissions are solicited that derive such interactions that relate to recent developments in mathematical theory and computational practice.

Conference topics include but are not limited to the following.
