In the third paragraph following Eq. ( This is incorrect. Instead, on one side of the kink, grows as -1=3 , where is the distance between the observation point and the kink. This divergence arises from the term in the Green's function inversely proportional to the distance between the observation point and the kink, which goes as 1=3 , combined with the discontinuous change in the source as one crosses the kink. A detailed analysis is in Ref. [1].
