Computer Algebra in Quantum Field Theory

This book focuses on advanced computer algebra methods and special functions that have applications in quantum field theory. It presents new methods for (infinite) multiple sums, multiple integrals, difference and differential equations.

Combines techniques methods from special functions and computer algebra applied to quantum field theory Contains survey articles written by mathematicians and physicists Describes algorithms and techniques developed by interdisciplinary teams of mathematicians, theoretical particle physicists and computer scientists Includes supplementary material: sn.pub/extras
