*“Constraining forces and a problem in fluid motion”*

**

/Abstract: //Several problems in mechanics can be understood as motion 
near a submanifold of a configuration space. In such cases one might be 
given a manifold with a Riemannian metric, a submanifold and a function 
whose minimum is the submanifold. One then considers possible motions 
whose kinetic energy is given by the metric and whose potential energy 
is given by the function. Such motions will oscillate about the 
submanifold.We shall begin by analyzing a simple motion in R^2 whose 
submanifold is the circle and whose potential energy is k times the 
square of the distance to the circle, where k is a large positive 
constant. We will see that the motion oscillates about the circle with a 
frequency \sqrt(k) and amplitude 1/k so as k goes to infinity, the 
motion is constrained to thecircle. Then we shall look at incompressible 
inviscid fluid motion with free boundary in a domain \Omega included in 
R^3. Here the configuration space will be all volume preservingmaps of 
\Omega into R^3 and the submanifold D will be volume preserving 
diffeomorphisms of \Omega. The potential energy function V(\eta) will be 
k times the area of the boundary of \eta(\Omega) where k again is a 
large positive constant. The motion determined by this is incompressible 
fluid motion with surface tension proportional to k. We shall derive the 
equations of the motion and show that if the the boundary of \Omega has 
constant mean curvature (and is therefore a sphere), then as k gets 
large the motion converges to a curve in D; that is, as k goes to 
infinity the motion converges to a motion with fixed boundary./
