I don't understand

edit

From looking at good books (like Joachain, 1975) on scattering theory on Schwinger variatonal principle, I really don't understand what is the relation of this article with what is known in the literature under this name. Is the Schwinger variational principles really so simple? Since I don't know what is SAB, I cannot judge. But as far as I know I am thinking at a crackpot!


  • I agree with the user above, the value of SAB should be indicated although if its an action perhaps is of the form:

 

where X is the position operator and V is the potential..

Also, a definition of S needs to be given. Xxanthippe (talk) 22:59, 10 July 2011 (UTC).Reply
