Green's Functions and Ordered Exponentials
Green's Functions and Ordered Exponentials
This book presents a functional approach to the construction, use and approximation of Green's functions and their associated ordered exponentials. After a brief historical introduction, the author discusses new solutions to problems involving particle production in crossed laser fields and non-constant electric fields. Applications to problems in potential theory and quantum field theory are covered, along with new approximations for the treatment of color fluctuations in high-energy QCD scattering.
- Describes Green's functions, the basis for the modern description of interactions, and their applications
- Contains new solutions to problems involving particle production in crossed laser fields and non-constant electric fields
- A valuable reference text for graduate students and researchers working on causal interactions
