Periodic boundary-value problems for fourth-order differential equations with delay

We study the periodic boundary-value problem $$displaylines{ x^{(iv)}(t)+f(ddot{x})dddot{x}(t)+bddot{x}(t) +g(t,dot{x}(t-au))+dx=p(t)cr x(0)=x(2pi),quad dot{x}(0)=dot{x}(2pi),quad ddot{x}(0)=ddot{x}(2pi),quad dddot{x}(0)=dddot{x}(2pi), }$$ Under some resonant conditions on the asymptotic beha...
