• 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 ...
    • 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 , ...
