#### Abstract:

The celebrated Kerékjártó theorem asserts that planar continuous periodic maps are continuously conjugated to a linear map. We will prove that if the periodic map is $C^k,k\in\{1,\ldots,\infty\}$ the conjugation can be choosed $C^k$.

The talk is based on a joint work with A. Cima, A. Gasull and R. Ortega.
