Fermionic strings with Fermionic mass points are introduced.   Now there are both spacelike oscillations as well as spin oscillations.    The notion of a world sheet, traced out by a string over time, is introduced.   Path integrals are defined with respect to the world sheet and lead to the Laplace equation.

Topics: 
  • The ground state of Fermionic strings
  • The action for a string
  • Path integral review
  • Path integrals in string theory lead to the Laplace equation
