SUMMARY:Seminar Analysis and Mathematical Physics: Vikram Giri (ETH Zürich
 )
DESCRIPTION:A common issue in convex integration methods (going back to Nas
 h) is the presence of unwanted high-high frequency interactions. These iss
 ues can prevent the methods from producing solutions with the optimum "Ons
 ager" regularity to a given system of PDEs. We will discuss these issues i
 n the setting of the 2D Euler equations and then discuss a linear Newton i
 teration designed to get rid of these unwanted interactions in this settin
 g. We will conclude by discussing applications to other PDEs. This is base
 d on joint works with Răzvan-Octavian Radu and Mimi Dai.
