We consider the three-dimensional stationary Vlasov–Poisson system of equations with respect to the distribution function of the gravitating matter , the local density , and the Newtonian potential , where , ( are the space–velocity coordinates), and f is a function q of the local energy . For a given function , we obtain sufficient conditions for p to be "extendable." This means that there exists a stationary spherically symmetric solution of the Vlasov–Poisson system depending on the local energy E such that ρ = p. [ABSTRACT FROM AUTHOR]
