Per Martin-Löf's work on the development of constructive type theory has had a tremendous impact on the fields of logic and the foundations of mathematics. It also has broader philosophical significance and important applications in areas such as computing science and linguistics. This volume draws together contributions from researchers whose work builds on the theory developed by Martin-Löf over the last twenty-five years. As well as celebrating the anniversary of the birth of the subject it covers many of the diverse fields which are now influenced by type theory. It is an invaluable record of current activity and includes contributions from N. G. de Bruijn and William Tait, both important figures in the early development of the subject. Also published for the first time is one of Per Martin-Löf's earliest papers.

Editorial Reviews

From the Publisher
"This is a fine collection of essays about and around Per Martin Ld"of's intuitionistic theory. This book is certainly a testimony to the vitality and fruitfulness of Martin-Ld"of's ideas in the foundations of mathematics and theoretical computer science." — Yvon Gauthier, Modern Logic, Vol 8, No 1/2 (Jan 98 - Apr 2000) 2000

"This work has made an important contribution to the fields of logic and the foundations of mathematics and is also of broader philosophical significance. Its depth and relevance can be seen by its increasing application to a variety of fields from computing science to linguistics."— athematical
