We are interested in singular positive solutions of a quasilinear elliptic equation with a singular coefficient where , , and . The differential operator includes the standard Laplace, m-Laplace and ℓ-Hessian operators. In the case , a solution of the problem gives a radial solution of . This problem has a one-parameter family of singular positive solutions and one exact singular solution. We obtain an intersection number of two singular solutions in the critical and supercritical cases. The main technical tool is a phase plane analysis.
