Ordered Exponentials
|
|
- Research performed during my doctoral studies at the Brown University
- My main research
is concentrated on derivation of a
hierarchy of
approximations of the exact Green's functions, when the external field is gauge
(as in
QCD) or gravitational. Both cases involve additional technical difficulties due to
non-commutativity, conveniently focused in (path) Ordered Exponentials (OEs). It
is possible
to map such matrix OEs into vertex operators, and to extract some additional
information from them, due to better knowledge of how to approximately
evaluate such operators.
