ordered exponential造句

The propagators can be expressed as time-ordered exponentials of the integrated Hamiltonian.
Note that a path-ordered exponential is a convenient shorthand notation common in physics which conceals a fair number of mathematical operations.
A mathematician would refer to the path-ordered exponential of the connection as " the holonomy of the connection " and characterize it by the parallel-transport differential equation that it satisfies.
where A is the connection 1-form and we take the Cauchy principal value of the contour integral and \ mathcal { P } \, \ exp is the path-ordered exponential.
The ordered exponential can be defined as the left product integral of the infinitesimal exponentials, or equivalently, as an ordered product of exponentials in the limit as the number of terms grows to infinity:
It's difficult to find ordered exponential in a sentence. 用ordered exponential造句挺难的

The "'Wilson loop "'variable is a quantity defined by the trace of a path-ordered exponential of a gauge field A _ \ mu transported along a closed line C:
If-\ operatorname { J } ( x ) is a smooth connection, expanding above quantity to second order in infinitesimal quantities | u |, | v | one obtains for the ordered exponential the identity with a correction term that is proportional to the curvature tensor.
It is possible to obtain the interaction picture for a time-dependent Hamiltonian " H " 0, S ( " t " ) as well, but the exponentials need to be replaced by the unitary propagator for the evolution generated by " H " 0, S ( " t " ), or more explicitly with a time-ordered exponential integral.
