  • Ticket #25457 – Description

    initial v15  
     1The main purpose of this ticket is to give the possibility of entering the components of a metric while declaring this metric on a parallelizable manifold.
     2
     3In this ticket, there is a method which determine the signature of a metric. So it is no more necessary to give the signature of your metric while declaring, Sage is able to compute it! Therefore Sage would give the truth class of the declaring metric: Riemannian metric or Lorentzian metric or pseudo-Riemannian metric or degenerate metric.
