Research in the area of abstract data types started about 20 years ago. Since then there has been continuous activity with strong influence both on the applications and the theoretical foundations of methodologies for software design. The Ninth Workshop on Specification of Abstract Data Types was held jointly with the Fourth COMPASS Workshop in Spain in 1992.
The main topics covered were: object-oriented specifications, rewriting methods, specification languages and associated tools, type systems, and algebraic specification of concurrency. This volumes contains four invited papers...

This volume, Petri Net Technology for Communication-Based Systems, is a state-of-the-artreportin the seriesAdvances in Petri Nets. It showshowvarious well-established and new Petri net notions and techniques can be used for m- elingcommunication-basedsystems, withspecialfocusonwork?owmanagement and business processes. In the last 6 years this topic has been studied by the DFG Forschergruppe Petri Net Technology in Berlin in close cooperation with the international c- munity. The main results of this cooperation were presented at the 1st and 2nd...

This volume contains selected papers of the International Workshop on "Categorical Methods in Computer Science - with Aspects from Topology" and of the "6th International Data Type Workshop" held in August/September 1988 in Berlin. The 23 papers of this volume are grouped into three parts: Part 1 includes papers on categorical foundations and fundamental concepts from category theory in computer science. Part 2 presents applications of categorical methods to algebraic specification languages and techniques, data types, data bases, programming, and process specifications....

This book contains a collection of 37 refereed full papers selected from the contributions presented at the 5th International Workshop on Graph Grammars and Their Applications to Computer Science, held in Williamsburg, Virginia, USA, in November 1994.
The book covers the whole spectrum of methods and techniques for the investigation of the structure of graphs and graph transformations. The papers are divided into nine topical sections on rewriting techniques, specification and semantics, software engineering, algorithms and architectures, concurrency, graph languages, pattern and graphics,...

Graphs are among the simplest and most universal models for a variety of s- tems, not just in computer science, but throughout engineering and the life sciences. When systems evolve we are interested in the way they change, to p- dict, support, or react to their evolution. Graph transformation combines the idea of graphs as a universal modelling paradigm with a rule-based approach to specify their evolution. The area is concerned with both the theory of graph transformation and their application to a variety of domains. The International Conferences on Graph Transformation aim at bringing -...

Graphs are widely used to represent structural information in the form of objects and connections between them. Graph transformation is the rule-based manipulation of graphs, an increasingly important concept in computer science and related fields. This is the first textbook treatment of the algebraic approach to graph transformation, based on algebraic structures and category theory.

Part I is an introduction to the classical case of graph and typed graph transformation. In Part II basic and advanced results are first shown for an abstract form of replacement systems, so-called...

In funf sorgfaltig aufeinander abgestimmten Teilen behandelt das Buch die wesentlichen mathematischen Elemente der formalen Spezifikation von Systemen und der Aussagen- und Pradikatenlogik, die fur das Verstandnis des formalisierten Problemlosens entscheidend und damit fur Informatiker unerlasslich sind. Eine Einfuhrung in die intuitive Mengentheorie vermittelt zunachst notwendige mathematische Grundlagen. Motiviert durch das Konzept von Datenstrukturen und abstrakten Datentypen werden dann algebraische Strukturen in der Informatik behandelt. Danach werden Aussagen- und Pradikatenlogik aus...

Since the early seventies concepts of specification have become central in the whole area of computer science. Especially algebraic specification techniques for abstract data types and software systems have gained considerable importance in recent years. They have not only played a central role in the theory of data type specification, but meanwhile have had a remarkable influence on programming language design, system architectures, arid software tools and environments. The fundamentals of algebraic specification lay a basis for teaching, research, and development in all those fields of...
