Q4: Why do you say indexes are Group-Valued? Isn’t inflation just a number? A4: Here goes. In the most famous case you *can* get away with a number. But that 8.9% style CPI nonsense is actually secretly a 1x1 matrix in GL(1,R). And that actually matters! Why? B/c Non-linearity. — PolitiTweet.org

A3 Cont.: “This is why index numbers will one day be properly understood as parallel translation in Fiber Bundles wrt Economic Gauge Potentials. But Zoe doesn’t become Cam morphing into Fatima when voting. So parallel transport is unavailable. Even in topological social choice.” — PolitiTweet.org

A4 Cont.: Only 1x1 matrices commute. NxN matrices do not! And if A.B isn’t B.A, the system goes non-linear. So if you have 2 countries with 2 currencies, the commutative case doesn’t work at all. You need to use Freeman Dyson’s system of Time Ordered Products to save inflation. — PolitiTweet.org
