Synopses & Reviews
A detailed exposition, with applications to problems in potential theory and quantum field theory.
Synopsis
This book provides a coherent account of the construction, use and approximation of Green's functions and their associated ordered exponentials. Topics covered include applications to problems in potential theory and quantum field theory, as well as particle production in crossed laser fields and non-constant electric fields. For graduates and researchers.
