Description
Summary:<p/> <p>We prove existence and uniqueness results in the presence of coupled lower and upper solutions for the general <it>n</it>th problem in time scales with linear dependence on the <it>i</it>th &#916;-derivatives for <it>i</it> = 1,2,&#8230;,<it>n</it>, together with antiperiodic boundary value conditions. Here the nonlinear right-hand side of the equation is defined by a function <it>f</it>(<it>t</it>,<it>x</it>) which is rd-continuous in <it>t</it> and continuous in <it>x</it> uniformly in <it>t</it>. To do that, we obtain the expression of the Green's function of a related linear operator in the space of the antiperiodic functions.</p>
