Logical Foundations of Proof Complexity

This book treats bounded arithmetic and propositional proof complexity from the point of view of computational complexity. The first seven chapters include the necessary logical background for the material and are suitable for a graduate course. Associated with each of many complexity classes are both a two-sorted predicate calculus theory, with induction restricted to concepts in the class, and a propositional proof system. The result is a uniform treatment of many systems in the literature, including Buss's theories for the polynomial hierarchy and many disparate systems for complexity classes such as AC0, AC0(m), TC0, NC1, L, NL, NC, and P.

He is author or many research papers, including his famous 971 paper "The Complexity of Theorem Proving Procedures," and the 1982 recipient of the Turing Award. He was awarded a Steacie Fellowship in 1977 and a Killam Research Fellowship in 1982 and received the CRM/Fields Institute Prize in A. He is a Fellow of the royal Society of London and the royal Society of Canada and was elected to membership in the National Academy of sciences (United States) and the American Academy of Arts and Sciences. Phuong Nguyen is a postdoctoral researcher at McGill University. He received his MSc and PhD degrees from University of Toronto in 2004 and 2008, respectively. He has been awarded postdoctoral fellowships by the Eduard Cech Center for Algebra and Geometry (the Czech Republic) and by the Natural Sciences and Engineering Research Council of Canada (NSERC).
