Zusammenfassung der Projektergebnisse

We consider singularities in the ElectroHydroDynamic equations. In a regime where we are allowed to neglect surface tension, and assuming that the free surface is given by an injective curve and that either the fluid velocity or the electric field satisfies a certain non-degeneracy condition, we prove that the fluid region is asymptotically a cusp. Our proofs depend on a combination of monotonicity formulas and a non-vanishing result by Caffarelli-Friedman. As a by-product of our analysis we also obtain a special solution with convex conical air-phase which we believe to be new.
