Canonical quantization with constraints

  1. Sep 14, 2008 #1
    let be the Lagrangian [tex] (1/2)m( \dot x ^{2} + \dot y^{2}) - \lambda (x^{2}+y^{2}-R^{2}) [/tex]

    with 'lambda' a Lagrange multiplier , and 'R' is the radius of an sphere.

    basically , this would be the movement of a particle in 2-d with the constraint that the particle must move on an sphere of radius 'R' , my doubt is that i do not know how to quantizy it since [tex] p_{\lambda}=0 [/tex]

    Have a look at the Wiki page for Dirac brackets and Dirac-Bergman quantization:
    http://en.wikipedia.org/wiki/Dirac_bracket
    It explains the essence of constrained quantization.

    See also this paper:
