Each term can be represented by a sum of Feynman diagrams. This series diverges asymptotically, but in quantum … See more This leads to the following Neumann series: Here we have $${\displaystyle t_{1}>t_{2}>\cdots >t_{n}}$$, so we can say that the fields are See more One can then express the state vector at time t in terms of the state vector at time t0, for t > t0, Then, the inner … See more • Schwinger–Dyson equation • Magnus series • Peano–Baker series • Picard iteration See more

The solution is Dyson’s formula: U I t;t0 =T exp i Z t t0 dt00H I t00 (3) where the T in front of the exponential is the time-ordering symbol. It is interpreted as ordering all terms in decreasing order of time, from left to right. As Coleman puts it, ’left-ist is latest’ or ’later on the left ...
