• Geometric assumptions and variational tools in Lorentzian geometry 

      Candela, Anna Maria (2014-10-02)
      During the past years there has been a considerable amount of research related to the problem of geodesic connectedness of Lorentzian manifolds. In particular, some geometric sufficient conditions have been introduced so ...
    • Gravitational Waves: completeness and connectedness by geodesics 

      Candela, Anna Maria (2016-09-13)
      Only few months ago some physicists gave the official announcement that gravitational waves exist, but, from a geometrical point of view, they have always been ``real objects'' and their properties have been widely ...
