Feynman integrals are indispensable for precision calculations in quantum field theory. They occur as soon as one goes beyond the leading order in perturbative quantum field theory. Feynman integrals are also fascinating from a mathematical point of view. They can be used to teach and illustrate a large part of modern mathematics with concrete non-trivial examples. In recent years therewere some exiting developments in the field of Feynman integrals, enlarging significantly our knowledge and understanding of Feynman integrals. Although there are some excellent older books on the subject [1–6], a modern introduction to the theory of Feynman integrals, which includes the recent developments, will be helpful.
