On steady states of van der Waals force driven thin film equations
European journal of applied mathematics
Let Ω ⊂ R N , N ≥ 2 be a bounded smooth domain and α > 1. We are interested in the singular elliptic equation with Neumann boundary conditions. In this paper, we gave a complete description of all continuous radially symmetric solutions. In particular, we constructed nontrivial smooth solutions as well as rupture solutions. Here a continuous solution is said to be a rupture solution if its zero set is nonempty. When N = 2 and α = 3, the equation has been used to model steady states of van derdoi:10.1017/s0956792507006936 fatcat:bak2pr4swjd7th5rd4d5repw2m
