Webculation), by Freeman Dyson in 1949. 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 ... WebSummary.

WebSummary. On the basis of canonical quantization of free fields, by means of the interaction picture which expresses the evolution of interacting fields in terms of the free field, the scattering matrix is first expressed in Dyson's formula as a perturbation series in a free-field Hamiltonian, then converted to Wick's operator expansion, and ...

In 1956, F.Spitzer fully described the maximum of a random walk with the help of a remarkable combinatorial theorem of H.F.Bohnenblust. It turns out that the generalized Hunt-Dyson formula is an equivalent version of Bohnenblust-Spitzer theorem. granny\\u0027s catering kansas city
