In the context of a brane world and including an induced curvature term inthe brane action, we obtain the effective lagrangian for the Goldstone bosons(branons) associated with the spontaneous breaking of the translationalinvariance in the bulk. In addition to the branons, this effective action hasSkyrmion-like solitonic states which can be understood as holes in the brane.We study their main properties such as mass and size, the Skyrmion-branoninteraction and their possible fermionic quantization. We also consider stateswhere the brane is wrapped around the extra dimensions and their relation withthe brane-skyrmions. Finally, we extend our results to higher-dimensionalbranes, such as those appearing in M-theory, where brane-skyrmions could alsobe present.Comment: 35 pages, 7 figures. Revised version. Appendix and new references included. To appear in Phys. Rev.
