MODELS OF CLUSTERS OF POINT MASSES WITH LARGE CENTRAL REDSHIFTS G. S. Bisnovatyi-Kogan and Ya. B. Zel'dovich Astrofizika, Vot. 5, No. 2, pp. 223-234, 1969 =2/a 0.006 r(g)/r=const~a
is the kinetic energy cutoff. In the Newtonian limit, formally reduces to Similarity between clusters in the box and clusters with cutoff Newtonian cluster in box GR cluster with cutoff
E(b)/N W(0)=const, each extremum gives birth to new dynamically unstable mode. At W(0)> 15.8 all models are stable.
Dynamic stability against perturbations with constant adiabatic invariants. Equivalent to constant entropy for stability of gaseous star Thermodynamic stability include processes leading to thermal equilibrium, smoothing temperature over the newtonian cluster or star
