| Abstract: | Convection-diffusion problems in a given time-dependent domain with initial and boundary values are considered. The characteristic difference schemes which are based on piecewise-linear interPOlation or local quadratic interPOlation are given with corresponding optimal error estimates. |

| Keywords: | moving boundary convection-diffusion equation characteristic finite difference schemes |
