A nonlinear degenerate Fokker-Planck equation in the whole space is analyzed. The existence of solutions to the corresponding implicit Euler scheme is proved, and it is shown that the semi-discrete solution converges to a solution of the continuous p

In this paper we investigate existence of solutions for the system: D t α u = div ( u ∇ p ) , D t α p = − ( − Δ ) s p + u 2 , in T 3 for 0 s ≤ 1 , and 0 α ≤ 1 . The term D t α u denotes the Caputo derivative, which models memory effect

In this manuscript we consider an isotropic modification for the Landau equation with Coulomb potential in three space dimensions. Global in time existence of weak solutions for even initial data is shown by employing a time semi-discretization of th

In this manuscript we investigate the regularization of solutions for the spatially homogeneous Landau equation. For moderately soft potentials, it is shown that weak solutions become smooth instantaneously and stay so over all times, and the estimat

In this manuscript we consider a porous medium equation with non-local diffusion effects given by a fractional heat operator $\partial_t + (-\Delta)^s$ in two space dimensions. Global in time existence of weak solutions is shown by employing a time s

We consider the equation $$\displaystyle u_t = \mathrm{div}\,(a[u]\nabla u - u\nabla a[u]),\qquad -\Delta a = u. $$ This model has attracted some attention in the recent years and several results are available in the literature. We review recent resu
