Title: Regularity of Koch-Tataru Solutions to the 3D Navier-Stokes Equations Revisited
Speaker: Professor Zoran Grujic
Speaker Info: University of Virginia
Brief Description:
Special Note:

Koch-Tataru solutions are global-in-time small data mild solutions to the 3D NSE emanating from small data in $BMO^{-1}$. There have been several recent works in which the regularizing-decay rate estimates for Koch-Tataru solutions have been obtained. Spatial analyticity of solutions then follows as a consequence. I will present a different approach in which the spatial analyticity is obtained directly together with explicit estimates on the time-evolution of the domain of analyticity. The regularizing-decay rate estimates will then follow at once.
