The Kappa Symmetric transformations would be:
It is also clear that:
If we let
Now, to determine , we see that:
Switching to the exterior derivative ("d") notation,
here is a 2-form, independent of the worldsheet metric. Introducing a three-form , we obtain the desired equation through Stokes' Theorem\\. is the boundary of / . In 10 dimensions, a Majorana spinor satisfies:
Where is a real number with an absolute value of 1. In order to ensure that is closed, i.e., that , which can be trivjially seen from explicitly writing the superspace embedding function in terms of and .
itself would be given by:
We finally conclude that this modified action is invariant under the following kappa symmetric transformations:
