摘要
In this paper, we extend the study of generalized Killing spinors on Riemannian Spin (c) manifolds started by Moroianu and Herzlich to complex Killing functions. We prove that such spinor fields are always real spin (c) Killing spinors or imaginary generalized Spin (c) Killing spinors, providing that the dimension of the manifold is greater or equal to 4. Moreover, we examine which Riemannian Spin (c) manifolds admit imaginary and imaginary generalized Killing spinors.
