Query: Perturbed Lane-Emden equations as a boundary value problem with singular
  endpoints   The paper presents the solution for the existence of analytic solutions for
some generalized Lane-Emden (LE) equation. Such solutions exists on the unit
interval, which endpoints are singularities of the proposed perturbed LE
equation. The solution has many possible applications and one of the examples
was provided.
