(Of course, backing this up with actual profound re-interpretations is the hard part. :-) ) &amp;gt; That&amp;#x27;s interesting that…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1505.03840/"&gt;Paper and discussion history&lt;/a&gt;.

That&amp;#x27;s interesting that you do harmonic analysis on non-compact groups; I&amp;#x27;ve been meaning to learn more about that actually. I&amp;#x27;ve been working on group synchronization problems related to the ideas in this paper (http://arxiv.org/pdf/1505.03840.pdf), which briefly mentions how one might extend the concept to non-compact groups, but doesn&amp;#x27;t elaborate further.&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1505.03840/"&gt;Paper and discussion history&lt;/a&gt;.
