In this paper we continue the study of the initial value problem∂ t u=−∂ x (u 2+ 2σ∂ x u), u (0)= φ in the spaces Y s, γ= H s (R)∩ L γ 2 (R), where γ⩾ 0, s> 3 2 and L r 2 (R) denotes the set of all complex valued measurable functions such that∥ f∥ r 2=∝ R (1+ x 2) r¦ f (x)¦ 2 dx<∞. Our main result is the proof of well-posedness of the aforementioned problem in Y 2, γ, γ ϵ [0, 1]. The proof involves parabolic regularization, the Riesz-Thorin interpolation theorem and Kato's theory of linear evolution equations of “hyperbolic” type.
