We use the image sum method to reproduce Sushkov's result that for a masslessautomorphic field on the initial globally hyperbolic region $IGH$ of Misnerspace, one can always find a special value of the automorphic parameter$\alpha$ such that the renormalized expectation value$\langle\alpha|T_{ab}|\alpha\rangle$ in the {\it Sushkov state}``$\langle\alpha|\cdot|\alpha\rangle$'' (i.e. the automorphic generalization ofthe Hiscock-Konkowski state) vanishes. However, we shall prove by elementarymethods that the conclusions of a recent general theorem ofKay-Radzikowski-Wald apply in this case. I.e. for any value of $\alpha$ and anyneighbourhood $N$ of any point $b$ on the chronology horizon there exists atleast one pair of non-null related points $(x,x') \in (N\cap IGH)\times (N\capIGH)$ such that the renormalized two-point function of an automorphic field$G^\alpha_{\rm ren}(x,x')$ in the Sushkov state is singular. In consequence$\langle\alpha|T_{ab}|\alpha\rangle$ (as well as other renormalized expectationvalues such as $\langle\alpha|\phi^2|\alpha\rangle$) is necessarily singular{\it on} the chronology horizon. We point out that a similar situation (i.e.singularity {\it on} the chronology horizon) holds for states on Gott space andGrant space.Comment: 10 pages, LaTeX, 2 postscript figure

Stress - energy must be singular on the Misner space horizon even for automorphic fields
