A generalized Sitnikov problem

Gastón Beltritti, Fernando Mazzone, Martina Oviedo

In this paper we address a $n + 1$ -body gravitational problem governed by the Newton's laws, where $n$ primary bodies orbit on a plane $Π$ and an additional massless particle moves o…

Harnack's Inequality and A Priori Estimates for Fractional Powers of Non-symmetric Differential Operators

Hugo Aimar, Gastón Beltritti, Ivana Gómez +1

We obtain a new general extension theorem in Banach spaces for operators which are not required to be symmetric, and apply it to obtain Harnack estimates and a priori regularity fo…

Continuous time random walks and the Cauchy problem for the heat equation

Hugo Aimar, Gastón Beltritti, Ivana Gómez

In this paper we deal with anomalous diffusions induced by Continuous Time Random Walks - CTRW in $R^{n}$ . A particle moves in $R^{n}$ in such a way that the probabil…

Mean value formulas for solutions of some degenerate elliptic equations and applications

Hugo Aimar, Gastón Beltritti, Ivana Gómez

We prove a mean value formula for weak solutions of $div(|y|^{a}\grad u)=0$ in $R^{n + 1} = {(x, y) : x \in R^{n}, y \in R}$ , $- 1 < a < 1$ and balls centered at poin…
