An Integration of General Relativity and Relativistic Quantum Theory
  In previous work, the author extended the Poincare Lie algebra to include a four position operator as a natural extension to a large fifteen parameter Lie algebra of operators. We here propose to generalize the metric contained in those structure constants to be the Riemann metric as determined by Einstein's equations from the energy momentum tensor. This gives a new type of "Lie" algebra whose structure constants are space-time dependent. One obtains a new type of uncertainty principle in strong gravitational fields and an altered spectra for the hydrogen atom.
