Twistor Spinors with Zeros on Compact Orbifolds
Florin Belgun, Nicolas Ginoux and Hans-Bert Rademacher
We study compact spin orbifolds with finite singularity set carrying twistor-spinors. We show that any non-trivial twistor-spinor admits at most one zero which is singular unless the orbifold is conformally equivalent to a round sphere. We show the sharpness of our results through examples.
