%0 Journal Article %T On the hyperbolicity condition in linear elasticity %A Remigio Russo %J Le Matematiche %D 1991 %I University of Catania %X This talk, which is mainly expository and based on [2-5], discusses the hyperbolicity conditions in linear elastodynamics. Particular emphasis is devoted to the key role it plays in the uniqueness questions associated with the mixed boundary-initial value problem in unbounded domains. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/632
