A pseudo–index approach to fractional equations

Bartolo, Rossella (2015-03-10)

We study the multiplicity of weak solutions of a quasilinear elliptic problem on an open bounded domain of RN with smooth boundary ∂ Ω. Both the non– resonant and the resonant case are analyzed. Furthermore, we consider ...
Connectivity by geodesics on a class of globally hyperbolic spacetimes

Bartolo, Rossella (2016-04-14)

During the past years there has been a considerable amount of research related to the problem of geodesic connectedness of Lorentzian manifolds. This topic has wide applications in Physics, but for mathematicians its ...
Geodesic connectedness of a spacetime with a causal Killing vector field.

Bartolo, Rossella (2024)

We study the geodesic connectedness of a globally hyperbolic spacetime (M, g) admitting a complete smooth Cauchy hypersurface S and endowed with a complete causal Killing vector field K. The main assumptions are that ...
Recent results on (p,q)-Laplacian type equations

Bartolo, Rossella (2017-05-09)

Start ing from a new sum decomposit ion of W1,p(RN ) ∩W1,q(RN ) and using a variat ional approach, we invest igate the existence of mult ipleweak solut ions of a (p, q)–Laplacian equat ion on RN , for 1 < q < p < N , ...
