On the other hand we find that C γ0 = i1. Hence the Majorana condition becomes:
iψ = ψ |
(C.3.9) |
so that a Majorana spinor is just a real spinor multiplied by an overall phase
exp[−i π4 ]. |

Another identity which we can prove by direct evaluation is the following one:

=i χ x γa χt (C γ5)yz + χ y γa χt (C γ5)xz + χ x γa χz(C γ5)yt + χ y γa χz(C γ5)xt

Finally let us mention some relevant formulae for the derivation of the AdS4 × P3 compactification. With the above conventions we find:
|
|
γ0γ1γ2γ3 = iγ5 |
(C.3.13) |
and if we fix the convention: |

C.4 An so(6) Inversion Formula
In order to discuss the conversion of supergravity forms into MC forms of the supercoset a key role is played by an inversion formula which we utilize in the main text and we discuss in this appendix. Let us define the following set of 6 × 6 matrices:
|
ABα |
≡ ηAT τ α ηB |
|
|

|

|
ABαβ |
= ηAT τ αβ ηB |
