Well-posedness results for superlinear Fokker-Planck equations
Stefano Buccheri, Fernando Farroni, Gabriella Zecca
In this manuscript we deal with a class of nonlinear Fokker-Planck equations with the following structure \[ \partial_t u - ÷\big(M\nabla u+ E h(u)\big)=0, \] with a bounded el…
Recovering functions via doubly homogeneous nonlocal gradients
Stefano Buccheri, Augusto C. Ponce
We investigate a class of nonlocal gradients featuring distinct homogeneities at zero and infinity. We establish a representation formula for such doubly homogeneous operators and…
A metric counterpart of the Gu-Yung formula
Stefano Buccheri, Wojciech Górny
In this note we consider a generalisation to the metric setting of the recent work [Gu-Yung, JFA 281 (2021), 109075]. In particular, we show that under relatively weak conditions o…
Elliptic problems with superlinear convection terms
L. Boccardo, S. Buccheri, G. R. Cirmi
In this manuscript we deal with elliptic equations with superlinear first order terms in divergence form of the following type \[ -\mbox{div}(M(x)\nabla u)= -\mbox{div}(h(u)E(x))+f…
The best approximation of a given function in -norm by Lipschitz functions with gradient constraint
Stefano Buccheri, Tommaso Leonori, Julio D. Rossi
The starting point of this paper is the study of the asymptotic behavior, as , of the following minimization problem $$ \min\left\{\frac1{p}\int|\nabla v|^{p}+\frac12\i…
Viscosity solutions for nonlocal equations with space-dependent operators
Stefano Buccheri, Ulisse Stefanelli
We consider a class of elliptic and parabolic problems, featuring a specific nonlocal operator of fractional-laplacian type, where integration is taken on variable domains. Both el…
An Agmon-Allegretto-Piepenbrink principle for Schroedinger operators
Stefano Buccheri, Luigi Orsina, Augusto C. Ponce
We prove that each Borel function defined on an open subset induces a decomposition such that…
A singular Schrödinger-Maxwell system
Lucio Boccardo, Stefano Buccheri, Carlos Alberto dos Santos
In this paper we are concerned with existence of positive solutions for a Schrödinger-Maxwell system with singular or strongly-singular terms. We overcome the difficulty given by t…
A System of Local/Nonlocal -Laplacians: The Eigenvalue Problem and Its Asymptotic Limit as
S. Buccheri, J. V. da Silva, L. H. de Miranda
In this work, given , we prove the existence and simplicity of the first eigenvalue and its corresponding eigenvector , for the following local/no…
Gradient estimates for nonlinear elliptic equations with first order terms
Stefano Buccheri
We study existence and Lorentz regularity of distributional solutions to elliptic equations with either a convection or a drift first order term. The presence of such a term makes…
