A partial data problem in linear elasticityWe would like to thank Gunther Uhlmann for helpful suggestions and Masaru Ikehata for clarifying the history of the reduced Lamé system

We discuss the determination of the Lamé parameters of an elastic material by the means of boundary measurements. We will combine previous results of Eskin-Ralston and Isakov to prove inverse results in the case of bounded domains with partial data. Moreover, we generalise these results to domains with cylindrical ends.
