… Toroidal backgrounds for bosonic strings are used to understand target space duality as a symmetry of string field theory and to study explicitly issues in background independence. … Our starting point is the notion that the string field coordinates X(σ) and the momenta P(σ) are background independent objects whose field algebra is always the same; … We propose classical string field solutions relating any two toroidal backgrounds and discuss the space where these solutions are defined. …

… In the toroidal coordinates, a stability analysis is presented for very low-aspect-ratio tokamaks with circular cross section which is described by a surfacecurrent model (SCM) of axisymmetric equilibria. … Numericalresults show that, owing to the occurrence of the non-axisymmetric (w: l) un-stable modes, there exists no MHD-stable ideal SCM spheromak characterizedby zero external toroidal vacuum field. …
