Criteria on boundedness in terms of two measures for discrete systems Original Research Article

A new concept of boundedness, which unifies various boundedness notions and leads to other notions connecting them, is defined in terms of two measures. An attempt for discrete systems tries to offer sufficient conditions for obtaining boundedness criteria for such concepts. The employing of vector Lyapunov functions and a new comparison principle covers several known results in usual boundedness theory and, therefore, the present framework provides an additional unification.
