Abstract: The two-time Green function technique is formulated in nonextensive classical statistical mechanics within the optimal Lagrange multiplier framework. We introduce also the nonextensive classical version of the spectral density method, for a direct calculation of the Green functions, and its effectiveness is tested exploring the equilibrium properties of the classical ferromagnetic Heisenberg spin chain.
