Quasiperiodic function

In mathematics, a quasiperiodic function is a function that has a certain similarity to a periodic function. A function ${\displaystyle f}$ is quasiperiodic with quasiperiod ${\displaystyle \omega }$ if ${\displaystyle f(z+\omega )=g(z,f(z))}$, where ${\displaystyle g}$ is a "simpler" function than ${\displaystyle f}$. What it means to be "simpler" is vague.
