Yin, Jian Dong et Zhou, Zuo Ling, An equivalent condition for the self similar sets on the real line to have best coverings, Acta mathematica Sinica. English series (Print) , 29(9), 2013, pp. 1637-1646
In this paper, an equivalent condition for the self similar sets on the real line to have best coverings is given. As a result, it partly gives answer to the conjecture which was posed by Zhou and Feng [Zhou, Z. L., Feng, L.: Twelve open problems on the exact value of the Hausdorff measure and on topological entropy: A brief survey of recent results. Nonlinearity, 17(2), 493.502 (2004)].
