Language Engineering and Rigorous Software Development: International LerNet ALFA Summer School 2008

This volume contains the lecture notes from the courses o?ered at the Inter- tional Summer School on Language Engineering and Rigorous Software De- lopment, held in Piriap olis, Uruguay, from February 25 to March 1, 2008. The aim of the schoolwasthe dissemination of advancedscienti?c knowledge in the areas of programming languages and rigorous methods for software - velopment. The school was oriented to computer science graduate students and researchers, withaninterestinformaltechniquesforthedesignandconstruction of software systems as well as programming languages. The school was organized in the context of the LERnet (Language En- neering and Rigorous Software Development) project. LERnet is a project of the ALFA programme of the European Commission for co-operation between higher education institutions of the European Union and Latin America. The institutions that participate in the LERnet project are the following: - Chalmers Tekniska H] ogskola, Sweden - Institut National de la Recherche en Informatique et Automatique (INRIA), France - Universidad de Castilla-La Mancha, Spain - Universidad Catol ica de Santiago del Estero, Argentina - Universidad EAFIT, Colombia - Universidade Federal de Minas Gerais, Brazil - Universidade do Minho, Portugal - Universidad Nacional de San Luis, Argentina - Universidad Polit ecnica de Valencia, Spain - Universidad de la Republica , Uruguay - Universiteit Utrecht, The Netherlands The project oversees the mobility of PhD students from Latin America to the European Union and vice versa for a period of up to 18 months, to pursue
