Disconjugacy and Higher Order Dynamic Equations
In this chapter, we introduce the study of disconjugacy of nth order dynamic equations on time scales. Disconjugacy of ordinary differential equations is thoroughly studied and has a rich history. Much of what we develop in this chapter has been presented for ordinary differential equations in Coppel’s often cited monograph . The analogous theory for forward difference equations was developed by Philip Hartman  in a landmark paper which has generated so much activity in the study of difference equations.
