  • I would describe your function $s$ is the (absolute value of) the discrete derivative of functions on 4 points, arranged cyclically. This is a special case of a bunch similar functions, often denoted like this:
  • $\Delta_h f = f(x+h) - f(x),$
  • for various h and kinds of functions/domains/ranges.
  • The vectors you're looking at can be thought of as specifying a function on $\{0,1,2,3\}$, with $f(0) = \theta_0, f(1) = \theta_1$, etc.
  • This framing actually makes your conjecture accessible with stuff you probably already know, if you think back to calculus. But you explicitly didn't ask for a solution to your problem, so I'll not say more.

fixed my delta!
