Monte Carlo (MC) analysis of the Goldstone mode singularities for the transverse and the longitudinal correlation functions, behaving as G⊥ (k) ≅ a k-λ⊥ and G|| (k) ≅ b k-λ|| in the ordered phase at k → 0, is performed in the three-dimensional O(n) models with n=2,4,10. Our aim is to test some chall...
