From the reviews of the second edition: "The second edition (from 2008) contains a large additional chapter ... entitled 'Some Recent Developments', where alternative attempts at a rigourous formalism are presented, as well as recent applications. Summarizing, this is a good and insightful book for those familiar with path integrals and curious about the mathematic foundations of path integration." (Jacques Tempere, Belgian Physical Society Magazine, Issue 2, June, 2009) "The new edition goes way beyond the habitual corrections and additions ... . It is good to have this new book. Not only for the more recent results it contains, but also as a point of departure for so many questions that are still open in the realm of infinite dimensional oscillatory integrals." (Ludwig Streit, Zentralblatt MATH, Vol. 1222, 2011)
