Boundary controllability of Sobolev-type abstract nonlinear integrodifferential systems

Sufficient conditions are established for boundary controllability of various classes of Sobolevtype nonlinear systems including integrodifferential systems in Banach spaces. The results are obtained using the strongly continuous semigroup of operators and the Banach contraction principle. Examples are provided to illustrate the theory.  2002 Elsevier Science (USA).
