Introduction The theory of time scales which has recently received a lot of attention was introduced by Hilger in his . Thesis in 1988 in order to unify continuous and discrete analysis see Hilger 1 . Several authors have expounded on various aspects of this new theory see the survey paper by Agarwal et al. 2 and references cited therein. A book on the subject of time scales by Bohner and Peterson 3 summarizes and organizes much of the time scale calculus we refer also to the last book by Bohner and Peterson 4 for advances in dynamic equations on time scales. For the notation used below we refer to the next section that provides some basic facts on time scales extracted from Bohner and .
