摘要：

We explain how Feynman diagrams and the functional integral for quasi-Hermitian theories "know" about the metric eta. The answer turns out be that their derivation is based fundamentally on the Heisenberg equations of motion and the canonical equal-time commutation relations, which only take their standard form when matrix elements are evaluated using eta.
