Topological Soliton Configurations in 8-Spinor Nonlinear Model of thenonlinear 8-
spinor model, at small distances the closed-string approximation being used. Themass, the spin
Soliton configurations in generalized Mie electrodynamics of the

spinor identity, we show that the model includes the Skyrme
Twistor structures and boost-invariant solutions to field equations the set of fundamental (Maxwell, SL(2,ℂ)-Yang-Mills,
spinor Weyl and curvature) fields associated
The vacuum expectation value of the spinor massive field in the cosmic string spacetime expansion for the squared Dirac
operator in this background are also considered and the first three
