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...

Solomon Feferman has shaped the field of foundational research for nearly half a century. These papers, most of which were presented at the symposium honoring him at his 70th birthday, reflect his broad interests as well as his approach to foundational research, which places the solution of mathematical and philosophical problems at the top of his agenda. The contributions range from historical to technical to philosophical topics, with emphasis on proof theory and computational aspects.

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.
