We investigate the measure-theoretic entropy of the discrete geodesic flow with respect to invariant probability measures. binding of isaac mods achievements

"WebNondegenerate periodic orbits of a 3-d volume-preserving flow are either of hyperbolic or elliptic type: see Figure 11 for an illustration, and compare with the 2-d case of Figure 1. (It is not the case that elliptic orbits are necessarily surrounded by invariant tori—this classification records only linear behavior of the return map.) " - Flow invariance preserving
