We use the image sum method to reproduce Sushkov’s result that for a massless automorphic field on the initial globally hyperbolic region IGH of Misner space, one can always find a special value of the automorphic parameter α such that the renormalized expectation value 〈α|Tab|α〉 in the Sushkov state “〈α| · |α〉” (i.e. the automorphic generalization of the Hiscock-Konkowski state) vanishes.

As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...
