Astrophysics A two-dimensional singularity hypothesized in string theory.
- The simplest soliton is the domain wall with co-dimension one, and the next simplest is the vortex with co-dimension two, whereas the co-dimension three (four) soliton is called monopole (instanton).2006, M. Eto et al., “Solitons in Supersymmetric Gauge Theories”, in Particles, Strings and Cosmology, →ISBN, page 266:
