ON THE LAGRANGIAN FORMALISM FOR SPIN VARIABLES

Name: Work Video:
Duration: 3 min 30 s
Description: It is demonstrated that a modification of the class of permissible variations in the Schwinger variational principle permits one to include spin variables in the general Lagrangian formalism in the nonrelativistic as well as relativistic cases. (auth)
