By exploiting its conformal covariance, the equation can be posed on the round sphere Sn and the non-zero solutions at the ground level are given by Killing spinors, up to conformal diffeomorphisms.

Abstract
We prove a classification result for ground state solutions of the critical Dirac equation on Rn, n⩾ 2. By exploiting its conformal covariance, the equation can be posed on the round sphere Sn and the non-zero solutions at the ground level are given by Killing spinors, up to conformal diffeomorphisms. Moreover, such ground state solutions of the critical Dirac equation are also related to the Yamabe equation for the sphere, for which we crucially exploit some known classification results.File in questo prodotto:
