Rigidity of smooth critical circle maps
Journal of the European Mathematical Society, Tome 19 (2017) no. 6, pp. 1729-1783
We prove that any two C3 critical circle maps with the same irrational rotation number of bounded type and the same odd criticality are conjugate to each other by a C1+α circle diffeomorphism, for some universal α>0.
