This book constitutes the thoroughly refereed post-conference proceedings of the 17th Brazilian Symposium on Formal Methods, SBMF 2014, held in Maceio, Brazil, in September/October 2014. The 9 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 34 submissions. SBMF is an event devoted to the dissemination of the development and use of formal methods for the construction of high quality computational systems, aiming to promote opportunities for researchers with interests in formal methods to discuss the recent advances in this area.

This book constitutes the thoroughly refereed post-conference proceedings of the 21st International Workshop on Algebraic Development Techniques, WADT 2012, held in June 2012, in Salamanca, Spain. The 16 revised papers presented were carefully reviewed and selected from 25 presentations. The workshop deals with the following topics: foundations of algebraic specification; other approaches to formal specification including process calculi and models of concurrent, distributed and mobile computing; specification languages, methods, and environments; semantics of conceptual modeling methods and techniques; model-driven development; graph transformations, term rewriting and proof systems; integration of formal specification techniques; formal testing and quality assurance; validation, and verification.

Maude is a language and system based on rewriting logic. In this comprehensive account, you'll discover how Maude and its formal tool environment can be used in three mutually reinforcing ways: as a declarative programming language, as an executable formal specification language, and as a formal verification system. Examples used throughout the book illustrate key concepts, features, and the many practical uses of Maude.

This book constitutes selected papers from the 12th International Workshop on Rewriting Logic and Its Applications, WRLA 2020, held in Dublin, Ireland, in April 2020.Due to the COVID-19 pandemic the workshop took place virtually. The 11 full papers presented in this volume were carefully reviewed and selected from 16 submissions Rewriting logic is a natural model of computation and an expressive semantic framework for concurrency, parallelism, communication, and interaction. It can be used for specifying a wide range of systems and languages in various application fields.

This Festschrift volume contains 28 refereed papers including personal memories, essays, and regular research papers by close collaborators and friends of Jose Meseguer to honor him on the occasion of his 65th birthday. These papers were presented at a symposium at the University of Illinois at Urbana-Champaign on September 23-25, 2015. The symposium also featured invited talks by Claude and Helene Kirchner and by Patrick Lincoln. The foreword of this volume adds a brief overview of some of Jose's many scientific achievements followed by a bibliography of papers written by Jose.
