The discussion centers on Elie Cartan's assertion in "La Géométrie des espaces de Riemann" that a constant Ricci scalar curvature (R = cte) allows for a comparison between space-time and the hydrostatic description of a liquid. Participants question the validity of this comparison and the reliability of alternative interpretations over Cartan's established work. The term "cte" refers to a constant value, which is crucial in understanding the context of the discussion.
