This volume contains the papers accepted for presentation at the 6th Inter- tional Conference on Veri?cation, Model Checking and Abstract Interpretation (VMCAI 2005), which was held January 17-19, 2005 in Paris, France. VMCAI provides a forum for researchers from the communities of veri?- tion, model checking, and abstract interpretation, facilitating interaction, cro- fertilization, and advancement of hybrid methods that combine the three areas. With the growing need for formal methods to reason about complex, in?ni- state, and embedded systems, such hybrid methods are bound to be of great importance. VMCAI 2005 received 92 submissions. Each paper was carefully reviewed, being judged according to scienti?c quality, originality, and relevance to the symposium topics. Following online discussions, the program committee met in ' Paris,France,attheEcoleNormaleSup' erieureonOctober30,2004,andselected 27 papers. In addition to the contributed papers, this volume includes contributions by outstanding invited speakers: ' - Patrick Cousot (Ecole Normale Sup' erieure, Paris), Proving Program Inva- ance and Termination by Parametric Abstraction, Lagrangian Relaxation and Semide?nite Programming; - C. A.R. Hoare (Microsoft Research, Cambridge), The Verifying Compiler, a Grand Challenge for Computing Research; - Amir Pnueli (New York University and Weizmann Institute of Science), - straction for Liveness. The VMCAI 2005 program included an invited tutorial by Sriram K. Ra- mani (Microsoft Research,Redmond) on Model Checking, Abstraction and S- bolic Execution for Software. VMCAI 2005 was followed by workshops on Automatic Tools for Veri?- tion, Abstract Interpretation of Object-Oriented Languages, and Numerical & Symbolic Abstract Domains.

The refereed proceedings of the 10th International Symposium on Static Analysis, SAS 2003, held in San Diego, CA, USA in June 2003 as part of FCRC 2003. The 25 revised full papers presented together with two invited contributions were carefully reviewed and selected from 82 submissions. The papers are organized in topical sections on static analysis of object-oriented languages, static analysis of concurrent languages, static analysis of functional languages, static analysis of procedural languages, static data analysis, static linear relation analysis, static analysis based program transformation, and static heap analysis.

This book constitutes the refereed proceedings of the Third International Static Analysis Symposium, SAS '96, held in Aachen, Germany, in September 1996 in conjunction with ALP and PLILP.
The volume presents 22 highly-quality revised full papers selected from a total of 79 submissions; also included are three system descriptions and invited contributions by Alex Aiken (abstract only), Flemming Nielson, and Bernhard Steffen. Among the topics addressed are program analysis, incremental analysis, abstract interpretation, partial evaluation, logic programming, functional programming, and constraint programming.
