Abstract:
This article concerns the stability and periodicity of solutions to
the delay dynamic system
on a time scale. By the inequality technique for vectors, we obtain
some stability criteria for the above system. Then, by using the
Horn fixed point theorem, we present some conditions under which our
system is asymptotically periodic and its periodic solution is unique.
In particular, the periodic solution is positive under proper assumptions.
