Abstract:

We show that Arnold tongues for the family of double standard maps \[ f_{a,b}(x)=2x+a-(b/\pi )sin(2 \pi x)\] are connected. This proof is accomplished in the complex domain by means of quasiconformal techniques and depends partly upon the fact that the complexification of $f_{a,b}$, has only one critical orbit taking symmetry into account.
