Instantaneous convexity breaking for the quasi-static droplet model
Albert Chau, Ben Weinkove · arXiv (Cornell University) · 2022
We consider a well-known quasi-static model for the shape of a liquid droplet. The solution can be described in terms of time-evolving domains in $\mathbb{R}^n$. We give an example to show that convexity of the domain can be instantaneously broken.
