Query: The free boundary Euler equations with large surface tension   We study the free boundary Euler equations with surface tension in three
spatial dimensions, showing that the equations are well-posed if the
coefficient of surface tension is positive. Then we prove that under natural
assumptions, the solutions of the free boundary motion converge to solutions of
the Euler equations in a domain with fixed boundary when the coefficient of
surface tension tends to infinity.
