      Varholm, Kristoffer (Doctoral theses at NTNU;2019:250, Doctoral thesis, 2019)
    • On the Stability of Solitary Water Waves with a Point Vortex 

      Varholm, Kristoffer; Wahlén, Erik; Walsh, Samuel (Journal article; Peer reviewed, 2020)
      This paper investigates the stability of traveling wave solutions to the free boundary Euler equations with a submerged point vortex. We prove that sufficiently small‐amplitude waves with small enough vortex strength are ...
    • Smooth stationary water waves with exponentially localized vorticity 

      Ehrnstrom, Mats; Walsh, Samuel; Zeng, Chongchun (Peer reviewed; Journal article, 2020)
      We study stationary capillary-gravity waves in a two-dimensional body of water that rests above a flat ocean bed and below vacuum. This system is described by the Euler equations with a free surface. A great deal of recent ...
