Domain-specific

• Non-Linear Sigma Model
  • The Euler–Lagrange equations are the harmonic-map equations in the purely kinetic case. In two dimensions, the coupling is dimensionless, and perturbative renormalization connects the beta function for the target metric to its Ricci curvature; Friedan's work established this geometric renormalization-group viewpoint.
