(Elsevier, 2014)We consider Liouville-type and partial regularity results for then online arfourth-order problem Δ2u = |u|p−1u in Rn, where p>1 and n≥ 1.We give a complete classification of stableand finite Morse index solutions ...

(Elsevier, 2017)We consider the following slightly subcritical problem ((sic)epsilon) { -Delta u = beta(x)vertical bar u vertical bar(p-1-epsilon) u in Omega, u = 0 on partial derivative Omega, where Omega is a smooth bounded ...

(Elsevier, 2016)We construct codimension 1 surfaces of any dimension that minimize a periodic nonlocal perimeter functional among surfaces that are periodic, cylindrically symmetric and decreasing. These surfaces may be seen as a ...
-
(Birkhauser Verlag, 2017)The goal of this note is to study the asymptotic behavior of positive solutions for a class of semilinear elliptic equations which can be realized as minimizers of their energy functionals. This class includes the Fisher-KPP ...

(Elsevier, 2013)In this paper we are interested in propagation phenomena for nonlocal reaction–diffusion equations of the type: ∂u ∂t = J ∗ u −u+ f (x,u) t ∈ R, x ∈ RN, where J is a probability density and f is a KPP nonlinearity ...
-
(Elsevier, 2016)We prove sharp Holder continuity and an estimate of rupture sets for sequences of solutions of the following nonlinear problem with negative exponent Delta u =1/u(p) in Omega, p > 1. As a consequence, we prove the ...

(Springer, 2016)We study radial solutions of the problem Delta u + u(p) + u(q) = 0, u > 0 in R-N, where N >= 3 and N/N - 2 < p < N + 2/N - 2 < q. We show that if p is close to N/(N - 2), q is close to (N + 2)/(N - 2), and ...
-
(Oxford Univ Press, 2016)We establish existence and non-existence results for entire solutions to the fractional Allen-Cahn equation in R-3, which vanish on helicoids and are invariant under screw motion. In addition, we prove that helicoids are ...

(Springer, 2017)We study global minimizers of an energy functional arising as a thin sample limit in the theory of light-matter interaction in nematic liquid crystals. We show that depending on the parameters various defects are predicted ...
