Sommario:
- We prove that for the functions of the form $g(x) = h(x) + \frac{C}{x+i}$, where $h$ belongs to the continuous Wiener algebra $W_0$, the intersection of the frame set $\mathcal{F}_g$ with every hyperbola $\{α, β> 0 \mid αβ= c\}$ is open in the relative topology. In particular, this applies to all rational functions $g$.
