Let be continuous and nondecreasing, if , and be positive real numbers. We investigate the behavior when of the fundamental solutions of in satisfying . The main question is wether the limit is still a solution of the above equation with an isolated singularity at , or a solution of the associated ordinary differential equation which blows-up at .
