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 complexity classes range from AC0 for the weakest theory up to the polynomial hierarchy. Each bounded theorem in a theory translates into a family of (quantified) propositional tautologies with polynomial size proofs in the corresponding proof system. The theory proves the soundness of the associated 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. |

Sommario/riassunto |
|
Cole saw the trade unions as being critical to progress, but to realise their role they needed to change and the issue of trade union structure therefore became fundamental. He considered in this volume that trade union structure was a central problem of the labour movement - he described British trade unionism as a movement bereft of ideas and policy. He discusses the evolution in the trade unions to cover not only wages and working conditions but the organisation and control of industry. |
