Canonically Conjugate meaning

  1. Dec 6, 2012 #1
    Momentum and position are canonically conjugate in physics because they are the fourier transforms of each other.

    In the context of abstract algebra what would that mean. More precisely, Let G be the group they both (p and x) belong to and let ψ:G->G/H be the natural homomorphism where H is the kernel of ψ. Would p and x be in the same coset in the set of cosets G/H?

    Dang, I lost my train of thought and I'm not sure where I'm going with this now. I guess my question now is, please relate canonically conjugate in group theory to Fourier transforms.

    Thanks, Nate
