Effective actions for bosonic topological defects.

We consider a gauge field theory which admits p-dimensional topological defects, expanding the equations of motion in powers of the defect thickness. In this way we derive an effective action and effective equation of motion for the defect in terms of the coordinates of the p-dimensional worldsurface defined by the history of the core of the defect.
