Abstract: Fluid and solids have very different physical characteristics, and their continuum descriptions are usually treated separately. However, singular structures such as cusps on the surface of a fluid, and cusped creases in folds of skin show striking similarities. In this talk, we discuss some of the similarities between fluid dynamics and elasticity, and highlight differences in the mathematical description of the two. Finally, the visco-elastic flow of polymer solutions lies in the middle between fluid flow and elasticity. Making a connection between the two extremes provides new insights, which we exploit to describe the thinning of a polymeric thread.

Biography: J. Eggers is a professor of Applied Mathematics at the University of Bristol. His career has been devoted to the understanding of self-similar phenomena. He has made fundamental contributions to our mathematical understanding of free-surface flows, in particular breakup and coalescence of drops. His work is instrumental in establishing the study singularities as a research field fluid dynamics and applied mathematics.
Dr. Eggers has also worked on non-Newtonian flows as well granular flows, thin films, contact lines, and non-linear elasticty. He continues to have an interest in statistical physics, most recently dynamic arrest in glasses and gels. He is a member of the Academy of Arts and Sciences in Erfurt, Germany, and a Fellow of the American Physical Society.  and a recipient of the Stanley Corrsin award of the American Physical Society. In 2017, he has received the Stanley Corrsin Award of the American Physical Society, and in 2023, the Naylor Prize and lectureship of the London Mathematical Society.
