Description

  1. What is the algorithm for the quantization procedure using Lagrangian mechanics?
  2. What is the main benefit of the Lagrangian approach compared to the approach utilizing symmetrization postulate?
  3. How does one identify the variables that should become operators with the canonical commutator?
  4. What is the classical analog of the canonical commutation relation?
  5. What are the generalized node fluxes? How are they defined? How do they correspond to other possible variables (charges, currents, voltages, magnetic fluxes through inductors)?
