We study the geometric behavior for large times of the solutions of the following equation posed in the whole space RN, for N⩾1 when the initial data are nonnegative, continuous and compactly supported. We prove that, after a finite time, log(u) becomes a concave function in the space variable and converges to all orders of differentiability to a certain parabolic shape, so-called Barenblatt-type profile, which was described in Kamin et al. (1991) [20]. Extensions to more general fully nonlinear equations are considered.
