The Classical Isoperimetric Problem and its Nonlocal Variants

  • Preliminary results on Geometric Measure Theory:
    • Hausdorff measures,
    • tangent measures, 
    • rectifiable sets.
  • The theory of sets of finite perimeter. 
  • The De Giorgi's solution to the Isoperimetric Problem. 
  • Partial regularity theory of Lambda-minimizers of the perimeter functional. 
  • A nonlocal variant of the perimeter: the sharp interface Ohta-Kawasaki energy. 
  • Regularity of  local minimizers. 
  • The second variation of the perimeter and of the Ohta-Kawasaki energy.
