Symmetry and Grassmann numbers

Particle Physics 3: Supersymmetry and Grand Unification (Spring, 2010)

April 19, 2010

Professor Susskind reviews the mathematical concepts of symmetry in preparation for the development of supersymmetry.   Then he introduces the mathematical concept of Grassmann numbers, which are used in the description of fermionic fields.

  • Continuous symmetries and generators (Lie algebra)
  • Grassmann numbers (anti-commuting numbers)
