Abstract By using the theory of variable exponent Sobolev spaces and the critical point theory,
periodic solutions for Kirchhoff-type p(t)-Laplacian systems are investigated. When the nonlinearity is
sublinear near zero or the nonlinearity is superlinear at infinity, the existence of infinitely many periodic
solutions for this system is obtained.
