-convergence for higher order nonlocal phase transitions

Hardy Chan, Serena Dipierro, Mattia Freguglia +2

For every , we study the asymptotic behavior of the -rescaled sum of the -fractional Allen-Cahn energy and the squared -norm of its first variation…

On a class of (non)local superposition operators of arbitrary order

Serena Dipierro, Sven Jarohs, Enrico Valdinoci

In this paper we introduce a very general setting dealing with the superposition of operators of any positive order and provide a systematic study of them. We also provide examples…

Stability and Self-Organized Patterns in Coupled Ecohydrological--Fire Dynamics: A Model of Vegetation--Rainfall--Bushfire Interactions

Serena Dipierro, Enrico Valdinoci

This paper investigates the conditions for the stability and emergence of patterns in a new three-component reaction-diffusion system. The system describes the coexistence and inte…

Density estimates for a (non)local variational model with degenerate double-well potential

Serena Dipierro, Alberto Farina, Giovanni Giacomin +1

In this paper we provide density estimates for a class of functions which includes all the minimizers of the energy $\mathcal{E}_s^p(u,Ω):=(1-s)\left(\frac{1}{2}\int_Ω\int_Ω\frac{|…

Weighted nonlocal area functionals without the triangle inequality

Serena Dipierro, Enrico Valdinoci, Mary Vaughan

We consider a weighted nonlocal area functional in which the coefficients do not satisfy the triangle inequality. In the context of three phase transitions, this means that one of…

-convergence of the non-local Massari functional and applications to inhomogeneous Allen-Cahn equations

Serena Dipierro, Enrico Valdinoci, Riccardo Villa

We present several asymptotic results concerning the non-local Massari Problem for sets with prescribed mean curvature. In particular, we show that the fractional Massari functiona…

Napoleonic Constructions in the Hyperbolic Plane

Serena Dipierro, Lyle Noakes, Enrico Valdinoci

In the Euclidean setting, Napoleon's Theorem states that if one constructs an equilateral triangle on either the outside or the inside of each side of a given triangle and then con…
