Abstract: | Let the coordinatex=(x 0,x 1,x 2,x 3) of the Minkowski spaceM 4 be arranged into a matrix Then the Minkowski metric can be written as. Imbed the space of 2 × 2 Hermitian matrices into the complex Grassmann manifoldF(2,2), the space of complex 4-planes passing through the origin ofC 2×4. The closure ofM 4 inF(2,2) is the compactification ofM 4. It is known that the conformal group acts on . It has already been proved that onF(2,2) there is anSu(2)-connection whereZ is a 2 × 2 complex matrix andZ †the complex conjugate and transposed matrix ofZ. Restrict this connection to which is anSu(2)-connection on . It is proved that its curvature form satisfies the Yang-Mills equation.
