Given a representation of a group Gon a vector space V, a regular function f2O(V) is called G-invariant or simply invariant if f(v) = f(gv) for all g2G;v2V. We denote by O(V)G O(V) the subalgebra of invariant functions. The actual representation of Gis assumed to be ...

WebThe Sµ⌫ are 4⇥4matrices,becausetheµ are 4⇥4 matrices. So far we haven’t given an index name to the rows and columns of these matrices: we’re going to call them ↵, =1,2,3,4. We need a field for the matrices ( Sµ⌫)↵ to act upon. We introduce the Dirac spinor field ↵(x), an object with four complex components labelled by ↵ ...
