Abstract

In the previous paper, Krein space quantization has been studied for QED (Forghan et al. in Ann. Phys. 327:2388, 2012). In this paper, the relation between the vertex function and the electron self energy has been studied, showing that the Ward identity is correct for Krein space quantization.
