Topic: 

Water Waves: Instabilities of Stokes Waves

Description: 

The study of ocean waves, particularly surface waves, is crucial for predicting and preparing for natural disasters such as tsunamis. Although ocean waves naturally occur in three dimensions, there are instances when they can be analyzed within a two-dimensional framework. For example, waves that propagate from the epicenter of a storm can be treated as unidirectional. In this presentation, we will examine periodic traveling waves that occur at the free surface of an ideal (incompressible and inviscid) two-dimensional fluid of infinite depth. Specifically, we will introduce surface waves of permanent shape, also known as Stokes waves and discuss their stability.

 

Speaker biography: Anastassiya Semenova is in the second year of an Acting Instructorship (Postdoctoral Fellowship) at the Department of Applied Mathematics at the University of Washington. She has also been holding a PIMS-Simons Postdoctoral Fellowship since September 2023. Previously, she was a Postdoctoral Fellow at the Institute for Computational and Experimental Research in Mathematics (ICERM) at Brown University. Anastassiya has earned her PhD in Applied Mathematics from the University of New Mexico, where she studied nonlinear waves.
