We consider the Cauchy problem for one-dimensional dispersive equations with a general nonlinearity in the periodic setting. Our main hypotheses are both that the dispersive operator behaves for high frequencies as a Fourier multiplier by i| ξ| α ξ, with 1≤ α≤ 2, and that the nonlinear term is of the form∂ x f (u) where f is the sum of an entire series with infinite radius of convergence. Under these conditions, we prove the unconditional local well-posedness of the Cauchy problem in H s (T) for s≥ 1− α 2 (α+ 1). This leads to some global existence results in the energy space H α/2 (T), for α∈[2, 2].
