Viscous flow is extremely effective in deforming a freesurface into very sharp features such as tips or cups. Under increaseddriving such free surface singularities may turn unstable, andgive way to secondary structures. In particular, this may be turnedinto a method to 'manufacture' small things by using the nonlinearcharacter of the equations ...

We report on recent experimental and theoretical work onthe pinch-off of dilute solutions of flexible polymers. Owing tothestrong extensional hardening of such solutions, pinch-off of aliquid drop is delayed. Instead, long threads of uniformthicknessform, whose radius decreases exponentially in time. We derive arelationship between the thread ra...

Approximate random k-colouring of a graph G=(V,E) is a very well studied problem in computer science, discrete mathematics and statistical physics. It amounts to constructing a k-colouring of G which is distributed close to Gibbs distribution in polynomial time. In this talk, we deal with the problem when the underlying graph is an instance of E...
