    Functional Analysis - Fall 2014 - Spring 2015

      There is no textbook used in the course. The class follows a series of lectures by Professor Vladimir Sverak. The subject is presented with an emphasis on compact operators, Fredholm operators, and their applications in PDE. Some background in group representation on a Hilbert space is also introduced.

    Mathematical Fluid Mechanics - Fall 2015 - Spring 2016

      There is no textbook used in the course. The class follows a series of lectures by Professor Vladimir Sverak. The equations of motion of a fluid are derived. The class also goes in depth into the regularity theory of the Navier-Stokes equations and turbulence theory. I was not enrolled in this class, but took notes of the lectures carefully.


    Begining French - Fall 2015 - Spring 2016

      Here are some translation efforts made after I took the classes.

  • French translation of a few sections of the paper Jia-Sverak "Minimal L^3-initial data for potential Navier-Stokes singularities" 2013.
  • English translation of the paper Gallagher-Iftimie-Planchon "Non-explosion en temps grand et stabilité de solutions globales des équations de Navier-Stokes" 2002.
