Query: Numerical Study of Astrophysics Equations by Meshless Collocation Method
  Based on Compactly Supported Radial Basis Function   In this paper, we propose compactly supported radial basis functions for
solving some well- known classes of astrophysics problems categorized as
non-linear singular initial ordinary dif- ferential equations on a
semi-infinite domain. To increase the convergence rate and to decrease the
collocation points, we use the compactly supported radial basis function
through the integral operations. Afterwards, some special cases of the equation
are presented as test examples to show the reliability of the method. Then we
compare the results of this work with some results and show that the new method
is efficient and applicable
