13th International Workshop on Termination (WST) Centro Residenziale Universitario di Bertinoro (near Bologna, Italy) http://www.imn.htwk-leipzig.de/WST2013/ submission: July 22, 2013 notification: July 25, 2013 final version: August 10, 2013 workshop: August 29 - 31, 2013 The Workshop on Termination traditionally brings together, in an informal setting, researchers interested in all aspects of termination, whether this interest be practical or theoretical, primary or derived. The workshop also provides a ground for cross-fertilisation of ideas from term rewriting and from the different programming language communities. The friendly atmosphere enables fruitful exchanges leading to joint research and subsequent publications. The 13th Workshop on Termination will be held from August 29 to 31, 2013, at the Centro Residenziale Universitario di Bertinoro (Italy). It will be a joint workshop, together with the 3rd International Workshop on Foundational and Practical Aspects of Resource Analysis. The sessions of WST and FOPARA will be interleaved, this way facilitating the interaction between the two communities. ( complete CfP see http://www.imn.htwk-leipzig.de/WST2013/ )
