Abstract

We argue that in four dimensions bosonic strings can be bundled together in a manner which resembles the way how individual filaments become bundled together to form a cable. The energy of such a bundle of strings is described by its extrinsic geometry, and it involves both torsion and curvature contributions. This leads to ordinary four-dimensional field theories, that describe the bundles of strings in terms of closed knotted solitons, Examples of field theories that can be constructed in this manner include the Faddeev model and the Skyrme model.
