Unifying Theories Of Programming

This book provides a synthesis of the theory of programming. It aims to use mathematical theory of programming to provide a similar basis for specification, design and implementation of programs. It is wide ranging both in its subject matter and also in its approach and style. The first five chapters justify and introduce the main concepts and methods to be used within the text, relating the goal of unification to the achievements of other branches of science and mathematics. The remaining chapters introduce more advanced programming language features one by one. The main methods of programming are summarised and concluded in a manner suitable for those already familiar with programming semantics. Definitions are accompanied by examples and the theorems by meticulous proof.

This book constitutes the refereed proceedings of the 4th International Symposium on Unifying Theories of Programming, UTP 2012, held in Paris, France, in August 2012, co-located with the 18th International Symposium on Formal Methods, FM 2012. The 8 revised full papers presented together with 2 invited talks and one invited lecture were carefully reviewed and selected from 13 submissions.

This book constitutes the refereed proceedings of the 5th International Symposium on Unifying Theories of Programming, UTP 2014, held in Singapore, Singapore, in May 13, 2014, co-located with the 19th International Symposium on Formal Methods, FM 2014. The 7 revised full papers presented together with one invited talk were carefully reviewed and selected from 11 submissions. They deal with numerous formal notations and theories of programming, such as abstraction, refinement, choice, termination, feasibility, locality, concurrency and communication.

This book constitutes the thoroughly refereed post-proceedings of the First International Symposium on Unifying Theories of Programming, UTP 2006, held at Walworth Castle, County Durham, UK, in February 2006. The book presents 14 revised full papers. Based on the pioneering work on unifying theories of programming by Tony Haare and Jifeng He, UTP 2006 focused on the most significant results and raised awareness of the benefits of unifying theoretical frameworks.

This book constitutes the thoroughly refereed post-proceedings of the Second International Symposium on Unifying Theories of Programming, UTP 2008, held at Trinity College, Dublin, Ireland, in September 2008. The 15 revised full papers presented, together with two invited talks, were carefully reviewed and selected from 20 submissions. Based on the pioneering work on unifying theories of programming of Tony Hoare, He Jifeng, and others, the aims of this Symposium series are to continue to reaffirm the significance of the ongoing UTP project, to encourage efforts to advance it by providing a focus for the sharing of results by those already actively contributing, and to raise awareness of the benefits of such a unifying theoretical framework among the wider computer science and software engineering communities.

This book constitutes the refereed proceedings of the Third International Symposium on Unifying Theories of Programming, UTP 2010, held in Shanghai, China, in November 2010, in conjunction with the 12th International Conference on Formal Engineering Methods, ICFEM 2010. The 12 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 25 submissions. Based on the pioneering work on unifying theories of programming of Tony Hoare, He Jifeng, and others, the aims of this Symposium series are to continue to reaffirm the significance of the ongoing UTP project, to encourage efforts to advance it by providing a focus for the sharing of results by those already actively contributing, and to raise awareness of the benefits of such a unifying theoretical framework among the wider computer science and software engineering communities.

This volume contains papers presented at UTP 2019, the 7th International Symposium on Unifying Theories of Programming, held in Porto, Portugal, on the 8th of October 2019. This edition of the UTP symposium is in honor of Sir Tony Hoare, on the occasion of his 85th birthday. The papers contained in this volume were invited, and friendly refereed, original contributions sought from the UTP community. One of the papers is from the distinguished invited speaker Tony Hoare himself. Nine other additional papers compose this volume, covering several aspects of Unifying Theories of Programming.

This book constitutes the refereed proceedings of the 6th International Symposium on Unifying Theories of Programming, UTP 2016, held in Reykjavik, Iceland, in June 2016, in conjunction with the 12th International Conference on Integrated Formal Methods, iFM 2016. The 8 revised full papers presented were carefully reviewed and selected from 10 submissions. They deal with the fundamental problem of combination of formal notations and theories of programming that define in various different ways many common notions, such as abstraction refinement, choice, termination, feasibility, locality, concurrency, and communication. They also show that despite many differences, such theories may be unified in a way that greatly facilitates their study and comparison.
