摘要：We will present our study of the positive solutions of a class of nonlinear differential equations on their maximal intervals of the positive real line R+, in particular, the structure of singular solutions. These solutions are the radial solutions of the semilinear elliptic equation, which T. Matukuma proposed in 1935 for the description of certain stellar globular clusters in a steady state. They correspond to time-independent solutions of the Vlasov-Poisson system.
