Gilbert %J Abstract and Applied Analysis %D 2010 %I Hindawi Publishing Corporation %R 10.1155/2010/234015 %X We establish the existence of solutions to systems of second-orderdynamic equations on time scales with the right member , a жд-Carathéodoryfunction. First, we consider the case where the nonlinearity does not dependon the жд-derivative, жд(). We obtain existence results for Strum-Liouville andfor periodic boundary conditions. Finally, we consider more general systemsin which the nonlinearity depends on the жд-derivative and satisfies a lineargrowth condition with respect to жд(). Our existence results rely on notionsof solution-tube that are introduced in this paper. %U http://www.hindawi.com/journals/aaa/2010/234015/
