%0 Journal Article %T Controllability of nonlinear differential evolution systems in a separable Banach space %A Bheeman Radhakrishnan %A Krishnan Balachandran %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X In this article, we study the controllability of semilinear evolution differential systems with nonlocal initial conditions in a separable Banach space. The results are obtained by using Hausdorff measure of noncompactness and a new calculation method. %K Controllability %K semilinear differential system %K evolution system %K measure of noncompactness %U http://ejde.math.txstate.edu/Volumes/2012/138/abstr.html
