References for the methods and results involved are very good. It will be invaluable to both pure and applied probabilists, as well as to many people in analysis. ".This book certainly covers almost all major topics in the theory of random walk. Finally, for the non-specialist there exists now an unsurpassed brief introduction to probabilistic potential theory, in the context of simple random walk and Brownian motion, by Dynkin and Yushkevich. By now there is an extensive and nearly complete potential theory of recurrent random walk on locally compact groups, Abelian (, ) as well as non Abelian (, ). Chapters II and VII from the integers to the reals.Stone succeeded in extending the recurrent potential theory in But the major new development since the first edition occurred in 1969, when D. Feller, Breiman, Chung in the more general setting of random walk on the real line. On the other hand, much of the material of this book (foundations, fluctuation theory, renewal theorems) is now available in standard texts, e.g. It is true that a number of interesting questions remain open in the concrete setting of random walk on the integers. The development of the subject in the last decade would have required a treatment in a much more general con text. These references are to a supplementary bibliography, whose items are referred to as through. In this edition a large number of errors have been corrected, an occasional proof has been streamlined, and a number of references are made to recent pro gress.
