UV-regularization of field discontinuities
arXiv:hep-th/9701068 · doi:10.1142/S0217732397000480
Abstract
A nonperturbative regularization of UV-divergencies, caused by finite discontinuities in the field configuration, is discussed in the context of 1+1-dimensional kink models. The relationship between this procedure and the appearance of "quantum copies" of classical kink solutions is studied in detail and confirmed by conventional methods of soliton quantization.
