Symmetry Operators and Separation of Variables for Dirac's Equation on Two-Dimensional Spin Manifolds

Understand

A signature independent formalism is created and utilized to determine the general second-order symmetry operators for Dirac's equation on two-dimensional Lorentzian spin manifolds.

• The formalism is used to characterize the orthonormal frames and metrics that permit the solution of Dirac's equation by separation of variables in the case where a second-order symmetry operator underlies the separation.
• Separation of variables in complex variables on two-dimensional Minkowski space is also considered.
