Ian M. Anderson et al.How to Create a Two-Component Spinor
http://digitalcommons.usu.edu/dg_how/2
http://digitalcommons.usu.edu/dg_how/2Wed, 10 Oct 2012 10:00:12 PDT
Let (M, g) be a spacetime, i.e., a 4-dimensional manifold M and Lorentz signature metric g. The key ingredients needed for constructing spinor fields on the spacetime are: a complex vector bundle E -> M ; an orthonormal frame on TM ; and a solder form relating sections of E to sections of TM (and tensor products thereof). We show how to create a two-component spinor field on the Schwarzschild spacetime using the DifferentialGeometry package in Maple. PDF and Maple worksheets can be downloaded from the links below.
