Abstract: 
 In this paper, we discuss  the existence, nonexistence,
 and multiplicity of positive solutions  for a class of singular
 eigenvalue problems. Some of our theorems are new, while others
 extend earlier results obtained by Zhang and Kong [12].
 The interesting point is that the authors obtain the relation
 between the existence of solutions and the parameter $\lambda$.
 The arguments are based on the fixed point index theory and
 the upper and lower solutions method.
