%0 Journal Article %T On exponential stability of C_0-quasisemigroups in Banach spaces %A Mihail Megan %A Vincen£¿iu Cuc %J Le Matematiche %D 1999 %I University of Catania %X Inthis paper we study some stability concepts for linear systems the evolution which can be described by a C_0 -quasisemigroup. The results obtained may be regarded as generalizations of well known results of Datko, Pazy, Littman and Neerven about exponential stability of C_0 -semigroups. %K C_0-quasisemigroup %K Exponential stability %K L^p-stability %K l^p stability %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/327
