DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ONEPAS/5/">W
 ater waves with density stratification or localized vorticity</a>\nby Samu
 el Walsh (University of Missouri) as part of Online Northeast PDE and Anal
 ysis Seminar\n\n\nAbstract\nThis talk will serve as a general introduction
  to two areas of active research in water waves. In the ocean\, the presen
 ce of salt and temperature gradients can lead to substantial stratificatio
 n of the density. This phenomenon is well-known to have significant physic
 al implications. Indeed\, it makes possible enormous ``internal waves'' th
 at can dwarf even the largest waves seen on the surface. We will present a
 n overview of the mathematical work on this subject\, focusing primarily o
 n recent results regarding the existence of large-amplitude solitary strat
 ified waves.\n\nThe second part of the talk will discuss waves with locali
 zed distributions of vorticity. These include water waves with submerged p
 oint vortices\, dipoles\, vortex patches\, and those exhibiting a vortex s
 pike.\n\nThis is joint work with Robin Ming Chen\, Mats Ehrnström\, Jalal
  Shatah\, Kristoffer Varholm\, Erik Wahlén\, Miles H. Wheeler\, and Chon
 gchun Zeng.\n
