Sufficient conditions for controllability of semilinear second-order neutra
l functional differential systems in Banach spaces are established using th
e theory of strongly continuous cosine families. The results are obtained b
y using the Leray-Schauder alternative. (C) 2001 Elsevier Science Ltd. All
