Wikipedia:Articles for deletion/Regality theory
a Google Scholar search for "regal kungic" (without quotes) gives 6 papers, all by Agner Fog.  I assume that {{u|Agnerf}} is that person.  Regal/kalyptic gives similar results.  The ties to other research such as that of Peter Turchin appears to be /; I don't think Fog's research is mentioned by Turchin.  This should be deleted
