PeterMosses, renownedresearcherofSemanticsofProgrammingLanguagesand Algebraic Speci?cation Frameworks, turned 60 years old on November 3, 2008. To honor this event, many of Peter's coauthors, collaborators, close colleagues, and former students gathered in Udine, Italy on September 10, 2009 for a s- posium in his honor. The presentations were on subjects related to Peter's many technicalcontributionsand they were a tribute to his lasting impact onthe ?eld. Here is the program of the symposium: - Opening: Jens Palsberg - Session 1: (Chair: Jos e Luiz Fiadeiro) David Watt, Action Semantics in Retrospect H el eneKirchner, Component-BasedSecurityPolicyDesignwithColored Petri Nets Jos e Meseguer, Order-Sorted Parameterization and Induction - Session 2: (Chair: Andrzej Tarlecki) Martin Musicante, An implementation of Object-Oriented Action Semantics in Maude ChristianoBraga, AConstructiveSemanticsforBasicAspectConstructs Bartek Klin, Structural Operational Semantics for Weighted Transition Systems - Session 3: Fernando Orejas, On the Speci?cation and Veri?cation of Model Tra- formations Olivier Danvy, Towards Compatible and Interderivable Semantic Spe- ?cations for the Scheme Programming Language Mark van den Brand, Type Checking Evolving Languages with MSOS Edward Hermann Haeusler, Action Algebras and Model Algebrasin - notational Semantics - Closing: Peter Mosses ManythankstoMarinaLenisafromthe UniversityofUdine whocoordinated the local arrangements. We also thank the Amga spa and the Net spa of Udine, the Municipality of Udine, the International Centre for Mechanical Sciences of Udine, and the Fondazione Crup for their ?nancial support. The 17 invited chapters of this Festschrift represent the proceedings of the symposium. Somecontributorswereunabletoattendthe event."

This book constitutes the refereed proceedings of the 16th International Symposium on Static Analysis, SAS 2009, held in Los Angeles, CA, USA in August 2009 - co-located with LICS 2009, the 24th IEEE Symposium on Logic in Computer Science.

The 21 revised full papers presented together with two invited lectures were carefully reviewed and selected from 52 submissions. The papers address all aspects of static analysis including abstract domains, abstract interpretation, abstract testing, compiler optimizations, control flow analysis, data flow analysis, model checking, program specialization, security analysis, theoretical analysis frameworks, type based analysis, and verification systems.

This volume contains the proceedings of the 15th International SPIN Workshop on Model Checking of Software (SPIN 2008), which took place at the University of California, Los Angeles, August 10-12, 2008. The SPIN workshops form a forum for researchers and practitioners interested in model checking techniques for the veri?cation and validation of software systems. Model checking is the process of checking whether a given structure is a model of a given logical f- mula.The structure normallyrepresents a setof tasks executing in parallelin an interleaved fashion, resulting in a non-deterministic set of executions. The main focusoftheworkshopseriesissoftwaresystems, including models andprograms. Subjects of interest include theoretical and algorithmic foundations as well as toolsfor softwaremodel checking.The workshopin additionaimsto foster int- actions and exchanges of ideas with related areas in software engineering, such as static analysis, dynamic analysis, and testing. There were 41 submissions, including 38 full papers and 3 tool papers. Each submissionwasreviewedbyatleastthreeProgrammeCommitteemembers.The committee decided to accept 18 papers, including 17 regular papers and 1 tool paper. The programme also included ?ve invited talks (in alphabetical order): Matthew Dwyer (University of Nebraska) "Residual Checking of Safety Pr- erties," Daniel Jackson (MIT) "Patterns of Software Modelling: From Classic To Funky," Shaz Qadeer (Microsoft Research) "The Case for Context-Bounded Veri?cation of Concurrent Programs," Wolfram Schulte (Microsoft Research) "Using Dynamic Symbolic Execution to Improve Deductive Veri?cation," and Yannis Smaragdakis (University of Oregon) "Combining Static and Dynamic Reasoning for the Discovery of Program Properties."

This book constitutes the refereed proceedings of the 12th International Conference on Tools and Algorithms for the Construction and Analysis of Systems, TACAS 2005, held Austria in March/April 2006 as part of ETAPS. The 30 revised full research papers and four revised tool demonstration papers presented together with one invited paper were carefully reviewed and selected from a total of 118 submissions. The papers are organized in topical sections.

Static Analysis is a research area aimed at developing principles and tools for high-performance implementation and veri?cation of programming languages. The seriesofStatic AnalysisSymposiais aforumforpresentationanddiscussion of advances in the area. ThisvolumecontainsthepaperspresentedattheSeventhInternationalStatic Analysis Symposium (SAS 2000) which was held on June 29-July 1, 2000 at the University of California, Santa Barbara. Previous symposia were held in Venice, Pisa, Paris, Aachen, Glasgow, and Namur. The program committee met at Purdue University in March 2000 and - lected 20 papers from 52 submissionson the basis of four reviewsper paper. The program committee members were not allowed to author or co-author a subm- sion. In addition to the 20 contributed papers, this volume contains two invited papers by Daniel Jackson and Andreas Podelski. At the symposium, there was also an invited talk by Matthias Felleisen and a tutorial by Roy Dz-ching Ju. Special thanks to Wanjun Wang for helping me from start to ?nish.

This book constitutes the refereed proceedings of the 19th International Conference on Verification, Model Checking, and Abstract Interpretation, VMCAI 2018, held in Los Angeles, CA, USA, in January 2018.The 24 full papers presented together with the abstracts of 3 invited keynotes and 1 invited tutorial were carefully reviewed and selected from 43 submissions. VMCAI provides topics including: program verification, model checking, abstract interpretation, program synthesis, static analysis, type systems, deductive methods, program certification, decision procedures, theorem proving, program certification, debugging techniques, program transformation, optimization, and hybrid and cyber-physical systems.
