This lecture develops an algebraic approach to the energy spectrum of strings.  Raising and lowering operators are associated with the modes of the strings.  The lecture finishes with the basics of string interactions.

Topics: 
  • Raising and lowering operators
  • The tachyon problem
  • String interactions
