WebApr 30, 2024 · Figure 11.3. 1. The integral can be solved by either closing the contour in the upper half-plane, or in the lower half-plane. If we close the contour above, then the loop contour does not enclose the pole, and hence G ( x, x ′; t − t ′) = 0. According to Jordan’s lemma, we must do this if the exponent in the integrand obeys.
