AB - <p>In this paper, we study a generalized thin film equation which is relevant to capillary driven flows of thin films of power-law fluids. We prove that the generalized thin film equation in dimension d ≥ 2 has a unique C^1 source type radial self-similar nonnegative solution if 0 &lt; n &lt; 2p-1 and has no solution of this type if n ≥ 2p-1.</p>
