On the minimal diameter of finite covers
Yifei Cai, Qiliang Luo
We prove that every closed hyperbolic surface admits a sequence of finite covers with asymptotically optimal diameters.
A logistic equation with non-local operators of order near zero
Luigi Appolloni, Serena Dipierro, Enrico Valdinoci
In this paper we study an equation driven by a non-local operator of order "near zero" with mixed Dirichlet-Neumann boundary conditions, modelling a biological system consisting of…
Ground state solutions for Hartree type equations driven by superposition operators and Pohozaev Identity
Alessandro Cannone, Silvia Cingolani, Serena Dipierro
We investigate Hartree-type equations driven by a nonlocal operator , defined as a superposition of fractional Laplacians through a signed Borel measure . Under…
Homoclinic solutions for nonlocal equations and applications to the theory of atom dislocation
Serena Dipierro, Caterina Sportelli, Enrico Valdinoci
The paper proves the existence of homoclinic solutions for fractional Laplacian equations with gradient-type forcing and shows how these solutions describe crystal configurations i…
Nonlocal minimal surfaces are generically unique, and smooth in one extra dimension
Serena Dipierro, Xavier Fernández-Real, Enrico Valdinoci
We study the fractional Plateau problem for -minimal sets with prescribed exterior datum. For fixed exterior data, minimizers need not be unique, and singularities may occur bey…
A free boundary analysis of tumor invasion driven by angiogenesis
Serena Dipierro, Edoardo Proietti Lippi, Caterina Sportelli +1
We discuss a free boundary model for tumor invasion that describes a cloud of cells that diffuse and, at the same time, are drifted along the vector field of the chemotactic direct…
