In theoretical physics, a skyrmion, conceived by Tony Skyrme, is a homotopically non-trivial classical solution of a nonlinear sigma model with a non-trivial target manifold topology i.e. a particular case of a topological soliton.
A skyrmion is a homotopically non-trivial classical solution of a nonlinear sigma model with a non-trivial target. This is in theoretical physics. This non-trivial target is manifold topology i.e. a particular case of a topological soliton. A skyrmion is conceived by Tony Skyrme.
