We here investigate the existence and uniqueness of the nontrivial, nonnegative solutions of a nonlinear ordinary differential equation:
satisfying a specific decay rate: with and . Here and . Such a solution arises naturally when we study a very singular self-similar solution for
a degenerate parabolic equation with nonlinear convection term
defined on the half line .
