DESCRIPTION:Prof. Jens Eggers\, School of Mathematics\, University of Bris
 tol \nAbstract: Fluid and solids have very different physical characterist
 ics\, and their continuum descriptions are usually treated separately. How
 ever\, singular structures such as cusps on the surface of a fluid\, and c
 usped 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. Fi
 nally\, the visco-elastic flow of polymer solutions lies in the middle bet
 ween fluid flow and elasticity. Making a connection between the two extrem
 es provides new insights\, which we exploit to describe the thinning of a 
 polymeric thread.\n\nBiography: J. Eggers is a professor of Applied Mathem
 atics at the University of Bristol. His career has been devoted to the und
 erstanding of self-similar phenomena. He has made fundamental contribution
 s 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 ma
 thematics.\n \nDr. 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 dyna
 mic 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 Socie
 ty.  and a recipient of the Stanley Corrsin award of the American Physica
 l Society. In 2017\, he has received the Stanley Corrsin Award of the Amer
 ican Physical Society\, and in 2023\, the Naylor Prize and lectureship of 
 the London Mathematical Society.
