Abstract
The classical Helmholtz model for wakes behind an obstacle in perfect fluid mechanics boils down in complex analysis into a Riemann problem with free boundary, the free boundary being the wake and being such that the Riemann map parametrizes it as arc-length parametrization. We generalize a method due to Coifman and Meyer to solve this problem for a class of non-smooth obstacles.
