Propagation in the Fisher-KPP equation with Mixed Operator
Begoña Barrios, Bryan Pichucho, Alexander Quaas
Our investigation focuses on the asymptotic spreading behavior of the Fisher-KPP equation with a mixed local-nonlocal operator in the diffusion (see the work by X. Cabré and J.-M.…
Higher regularity in nonlocal free boundary problems
Begoña Barrios, Xavier Ros-Oton, Marvin Weidner
We study the higher regularity in nonlocal free boundary problems posed for general integro-differential operators of order . Our main result is for the nonlocal one-phase (Ber…
Mixed local and nonlocal laplacian without standard critical exponent for Lane-Emden equation
Begoña Barrios, Leandro M. Del Pezzo, Alexander Quaas
In this paper, we investigate a mixed elliptic equation involving both local and nonlocal Laplacian operators, with a power-type nonlinearity. Specifically, we consider a Lane-Emde…
The limit as of the fractional convex envelope
Begoña Barrios, Leandro M. Del Pezzo, Alexander Quaas +1
We study the behavior of the fractional convexity when the fractional parameter goes to 1. For any notion of convexity, the convex envelope of a datum prescribed on the boundary of…
