I was given a problem by a professor to prove the following problem:
Anyway, I have done this but am supposed to remark on possible applications. I'm not sure to what I could apply this though. Maybe something to do with ergodics? Any suggestions would be appreciated.
If [itex]f:[0,1] \to \mathbb R[/itex] is a twice differentiable function, define [itex]\Gamma = \{y = f(x)\}[/itex] the curve associated to f. Show that the following are equivalent:
- [itex]m(\Gamma+\Gamma)>0[/itex]
- [itex]\Gamma +\Gamma[/itex] contains an open set.
- f is non-linear
