February 22/23: I lectured on existence/uniqueness theory for some minimization problems with pointwise one-sided constraints (obstacle problems) and pointwise constraints (harmonic maps, Stokes equations), with particular emphasis on the corresponding Euler-Lagrange equations. The topic next week is a theory ensuring the existence of critical points for "abstract" functionals (not necessarily integral functionals).
