Abstract:
We prove that the Pohlmeyer–Lund–Regge system is, up to coordinate changes, the unique two-component variational system of chiral type with an irreducible metric that admits a Lax representation with values in the algebra $\mathfrak{so}(3)$.
Keywords:
chiral-type system, integrable system, Lax representation, Pohlmeyer–Lund–Regge system.
