..."The book, written by one of the main researchers on the field, gives a complete account of the theory of r.e. degrees...The definitions, results and proofs are always clearly motivated and explained before the formal presentation; the proofs are described with remarkable clarity and conciseness. The book is highly recommended to everyone interested in logic. It also provide...(展开全部)

The first part consists of an introduction to the theory of computation and recursive function theory, including definitions of computable functions, Turing machines, partial recursive functions, recursively enumerable sets, the Kleene recursion theorem etc. The second part is a comprehensive study of recursively enumerable sets and their degrees.

This is the first in a series of books in which one of the most influential of contemporary art theorists revised from within the conceptions underlying the history of art. The author's basic idea is that the rigor of linear perspective cannot encompass all of visual experience and that it could be said to generate an oppositional factor with which it interacts dialectically: t...(展开全部)
