I am currently studying $p$ adic analysis, and wanted to know if there were good papers or books to read more about the $p$ adic solenoid, preferably its construction and physical structure?
I am familiar with Alain Robert's book and his exposition on the solenoid, but I tried looking for more information online and I didn't find anything substantial. Any other suggestions are very much appreciated, thank you.
I've just found a passing reference to the p-adic solenoid in Emily Riehl's book, Categories in Context (p.1). Apparently it came up in Eilenberg and Mac Lane's work leading to the universal coefficient theorem, which later led to them initiating category theory. The reference she gives is to Mac Lane's 2005 autobiography.
