Most of the preprints by the three authors are found in math.AP, give or take some in math.CA (classical analysis &amp; ODEs) and math.DG (diffgeo), with significant crossposting into math-ph and gr-qc. There is only a minority of &lt;https://arxiv.org/list/gr-qc/new&gt; that is crossposted into math.AP, but even fewer &lt;https://arxiv.org/list/math.AP/recent&gt; find themselves also in gr-qc. &gt; Sad side note Amusingly, Alan Coley&#x27;s [open problems in] &quot;Mathematical General Relativity&quot; &lt;https://arxiv.org/abs/1807.08628&gt;…</p><p><a href="https://hackerpaper.kaipfister.de/p/1004.1016/">Paper and discussion history</a>.
