• Maximal surfaces and graphs in a Lorentzian product -RxM 

      Lima Jr., Eraldo A. (2015-02-26)
      We will present several results for maximal surfaces in a Lorentzian product manifold -R×M. The main purpose is to characterize the slices as complete maximal surfaces satisfying a comparison between the growth of lenght ...
    • The topology and geometry of the space of null geodesics 

      LOW, ROBERT (2020-02-14)
      This talk will provide a general introduction to the space of null geodesics. I will begin with a discussion of the case of Minkowski space, a special case with a great deal of structure. After this, I will move on ...
