{\ displaystyle {\mathcal {T}}} {\mathcal T} called time-ordering operator, defining.
An approach to time‐ordered operators based upon von Neumann's infinite tensor product Hilbert spaces is used to define Feynman–Dyson algebras.
This series is called the Dyson series. Note that in the expansion the operators are time-ordered, so that in the product the ...
The evolution operator U(t)=Texp[i∫dtH(t)](Dyson series);; With T,bosons and fermions are unified together.Same theory with two differnt boundary conditions.
(7) and working to first order in ε,
You can extend it to n factors, ordering them so that later times (t) stand to the left of earlier
