Abstract: In this paper, we develop and analyze an arbitrary Lagrangian-Eulerian discontinuous Galerkin (ALE-DG) method with a time-dependent approximation space for one dimensional conservation laws, which satisfies the geometric conservation law. For the semi-discrete ALE-DG method, when applied to nonlinear scalar conservation laws, a cell entropy inequality, $\mathrm {L}^{2}$ stability and error estimates are proven. More precisely, we prove the sub-optimal ($k+\frac {1}{2}$) convergence for monotone fluxes and optimal ($k+1$) convergence for an upwind flux when a piecewise $P^k$ polynomial approximation space is used. For the fully-discrete ALE-DG method, the geometric conservation law and the local maximum principle are proven. Moreover, we state conditions for slope limiters, which ensure total variation stability of the method. Numerical examples show the capability of the method.
