摘要：
We present a general method to compute the elastic forces exerted on nematic point defects: these are the forces that set defects in motion, and so they are especially relevant to defect dynamics, a subject which is recently attracting much interest. These forces are mediated by the distortion introduced by defects in the director field; for example, they are responsible for the attraction between defects of opposite topological charge.
