Topologica Defects and Corrections to the Nambu Action
arXiv:gr-qc/9303017 · doi:10.1016/0375-9601(93)90138-P
Abstract
The effective action of a (1+2)-dimensional defect is obtained as an expansion in powers of the thickness.Considering non-straight solutions as the zero order term, the corrections to the Nambu action are found to depend on the curvature scalar and on the gaussian curvature .
