    "abstract": "An asymptotic theory is developed for a moving drop driven by a wettability\ngradient. We distinguish the mesoscale where an exact solution is known for the\nproperly simplified problem. This solution is matched at both -- the advancing\nand the receding side -- to respective solutions of the problem on the\nmicroscale. On the microscale the velocity of movement is used as the small\nparameter of an asymptotic expansion. Matching gives the droplet shape,\nvelocity of movement as a function of the imposed wettability gradient and\ndroplet volume.",
