Product Description: The problem of evaluating Feynman integrals over loop momenta has existed from the early days of perturbative quantum field theory. Although a great variety of methods for evaluating Feynman integrals has been developed over a span of more than fifty years, this book is a first attempt to summarize them...read more

Product Description: 'The sturgeon they sent was second grade fresh,' said the barman. 'Really, what nonsense/' 'Why nonsense?' '"Second grade fresh" that's what I call nonsense/ There's only one degree of freshness the first, and it's the last) (M. A...read more

Product Description: In recent years, for solving problems of algebraic topology and, in particular, difficult problems of homotopy theory, algebraic structures more complicated than just a topological monoid, an algebra, a coalgebra, etc., have been used more and more often...read more (view table of contents, read Amazon.com's description)

Product Description: The kinetics and mechanisms of reactions involving electronically excited radicals is a division of physical chemistry and high-energy chemistry, and was developed in the 1980s. Advances in the field are closely related to the solution of fundamental problems concerning the theory of electronic structure and reactivity, as well as the practical tasks of using flash and laser light sources and the application of various materials in nuclear and aerospace engineering...read more
