Typically I understand that projection operators are defined as
[tex]P_-=\frac{1}{2}(1-\gamma^5)[/tex]
[tex]P_+=\frac{1}{2}(1+\gamma^5)[/tex]
where typically also the fifth gamma matrices are defined as
[tex]\gamma^5=i\gamma^0\gamma^1\gamma^2\gamma^3[/tex]
and.. as we choose different representations the projection operators are.. sometimes in nice form where there is only one identity element however what happens when in certain representations it doesn't come out nicely like that how do I interpret which type of spinors are which chiraliity and such. .. anyways and what are some good materials. (shorter the better) on something complete on clifford algebra and it's representations and all the other things like charge conjugation and such.
