How to deal with conflicting “no-slip” Navier-Stokes boundary value constraints?
The no-slip boundary value constraint for Navier-Stokes solutions was explained in my fluid dynamics class as a requirement to match velocities at the interfaces.
Now that my class is done, I've been ...

Surface tension of N non-mixing fluids
I am a mathematician, not a physicist, so please be gentle with me if I write something wrong.
Consider a bounded, regular container $\Omega$, which is filled with the fluids $F_1,...,F_N$ which do ...
