This Festschrift volume is published in honor of Catherine A. Meadows and contains essays presented at the Catherine Meadows Festschrift Symposium held in Fredericksburg, VA, USA, in May 2019.Catherine A. Meadows has been a pioneer in developing symbolic formal verification methods and tools. Her NRL Protocol Analyzer, a tool and methodology that embodies symbolic model checking techniques, has been fruitfully applied to the analysis of many protocols and protocol standards and has had an enormous influence in the field. She also developed a new temporal logic to specify protocol properties, as well as new methods for analyzing various kinds of properties beyond secrecy such as authentication and resilience under Denial of Service (DoS) attacks and has made important contributions in other areas such as wireless protocol security, intrusion detection, and the relationship between computational and symbolic approaches to cryptography. This volume contains 14 contributionsauthored by researchers from Europe and North America. They reflect on the long-term evolution and future prospects of research in cryptographic protocol specification and verification.

It is one of several “symbolic approaches” to security protocol analysis in which the underlying details of cryptographic primitives are abstracted away, allowing a focus on potential flaws in the communication patterns between participants.

This Festschrift is dedicated to Gul Agha in recognition of his outstanding research and teaching impact. Gul Agha received his undergraduate degree at Caltech in 1977 and his A.M., M.S. and Ph.D. degrees at the University of Michigan, Ann Arbor. His thesis led to the MIT Press book Actors: A Model of Concurrent Computation in Distributed Systems, a work cited nearly 5000 times. After researcher and lecturer appointments at MIT and Yale, he moved to the University of Illinois, Urbana-Champaign, where he started as an assistant professor in 1989 and subsequently become a full professor and the founding director of the Open Systems Laboratory. The team’s goal is to develop concurrent programming languages and systems that support applications with high-performance, fault-tolerance or real-time requirements, and this work has been very influential across domains such as Software Engineering, Formal Methods, Programming Languages, Concurrency Theory, Distributed Systems, and Cyber-Physical Systems. Gul Agha is a Fellow of the IEEE and a Fellow of the ACM, other honors include the IBM Faculty Award, the ONR Young Investigator Award, and the ACM Recognition of Service Award.Over the course of his career Gul has been a highly impactful mentor, and he has collaborated in research and in publications with a wide range of scientists and engineers, in academia and in industry. Beyond his deep expertise, they have been inspired by his well-rounded intellect, philosophy of life, and sense of humor, and their successes are reflected in the papers contributed to this volume.

Joseph Goguen is one of the most prominent computer scientists worldwide. His numerous research contributions span many topics and have changed the way we think about many concepts. Our views about data types, programming languages, software specification and verification, computational behavior, logics in computer science, semiotics, interface design, multimedia, and consciousness, to mention just some of the areas, have all been enriched in fundamental ways by his ideas.This Festschrift volume - published to honor Joseph Goguen on his 65th Birthday on June 28, 2006 - includes 32 refereed papers by leading researchers in the different areas spanned by Joseph Goguen's work. The papers address a broad variety of topics from meaning, meta-logic, specification and composition, behavior and formal languages, as well as models, deduction, and computation.The papers were presented at a Symposium in San Diego, California, USA in June 2006. Both the Festschrift volume and the Symposium allow the articulation of a retrospective and prospective view of a range of related research topics by key members of the research community in computer science and other fields connected with Joseph Goguen's work.

This volume contains the 43 papers written by close collaboratorsand friends of UgoMontanariincelebrationofhis65thbirthday.Insomesense,thevolumeisa re?ection, with gratitude and admiration, on Ugo's highly creative, remarkably fruitful and intellectually generous life, which is thriving as strongly as ever. It provides a snapshot of the manifold research ideas that have been deeply in?uenced by Ugo's work. In a sense the book gives a vantage point from which to foresee further developments to come: by Ugo himself, and by many other people encouraged and stimulated by his friendship and example. The volume consists of seven sections, six of which are dedicated to the main research areas to which Ugo has contributed. Each of these six sections starts with a contribution by one of Ugo's closer collaborators providing an account of Ugo's contribution to the area and brie?y describing the papers in the section. The six scienti?c sections and the respective editors are the following: - Graph Transformation (Andrea Corradini) - Constraint and Logic Programming (Francesca Rossi) - Software Engineering (Stefania Gnesi) - Concurrency (Roberto Gorrieri) - Models of Computation (Roberto Bruni and Vladimiro Sassone) - Software Veri?cation (Gian-Luigi Ferrari) The ?nal section,edited by Fabio Gadducci,contains somelaudatio or memories of working experiences with Ugo, as well as three more technical contributions.

This book gives a comprehensive account of Maude, a language and system based on rewriting logic. Many examples are used throughout the book to illustrate the main ideas and features of Maude, and its many possible uses. Maude modules are rewrite theories. Computation with such modules is - cient deduction by rewriting. Because of its logical basis and its initial model semantics,aMaudemodulede?nesaprecisemathematicalmodel.Thismeans that Maude and its formal tool environment can be used in three, mutually reinforcing ways: • as a declarative programming language; • as an executable formal speci?cation language; and • as a formal veri?cation system. Maude’s rewriting logic is simple, yet very expressive. This gives Maude good representational capabilities as a semantic framework to formally represent a wide range of systems, including models of concurrency, distributed al- rithms, network protocols, semantics of programming languages, and models of cell biology. Rewriting logic is also an expressive universal logic,making Maude a ?exible logical framework in which many di?erent logics and - ference systems can be represented and mechanized. This makes Maude a useful metatool to build many other tools, including those in its own formal tool environment. Thanks to the logic’s simplicity and the use of advanced semi-compilation techniques, Maude has a high-performance implementation, making it competitive with other declarative programming languages.

This book constitutes the refereed proceedings of the 12th International Conference on Algebraic Methodology and Software Technology, AMAST 2008, held in Urbana, IL, USA, in July 2008. The 28 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 58 submissions. Among the topics covered are all current issues in formal methods related to algebraic and logical foundations, software technology, and to programming methodology including concurrent and reactive systems, evolutionary software/adaptive systems, logic and functional programming, object paradigms, constraint programming and concurrency, program verification and transformation, programming calculi, specification languages and tools, formal specification and development case studies, logic, category theory, relation algebra, computational algebra, algebraic foundations for languages and systems, coinduction, theorem proving and logical frameworks for reasoning, logics of programs, as well as algebra and coalgebra.

This Festschrift volume, published in honor of Carolyn Talcott on the occasion of her 70th birthday, contains a collection of papers presented at a symposium held in Menlo Park, California, USA, in November 2011.Carolyn Talcott is a leading researcher and mentor of international renown among computer scientists. She has made key contributions to a number of areas of computer science including: semantics and verification of progamming languages; foundations of actor-based systems; middleware, meta-architectures, and systems; Maude and rewriting logic; and computational biology.The 21 papers presented are organized in topical sections named: Essays on Carolyn Talcott; actors and programming languages; cyberphysical systems; middleware and meta-architectures; formal methods and reasoning tools; and computational biology.
