"In this paper we study a system of delay dynamic equations on the time scale $\\T$ of the form $$y^{\\Delta}(t)=f(t,y_{\\tau}(t)),$$ where $f\\colon\\mathbb{T}\\times\\mathbb{R}^n\\rightarrow\\mathbb{R}^n$, $y_\\tau(t)=(y_1(\\tau_1(t)),\\ldots,y_n(\\tau_n(t)))$ and $\\tau_i\\colon\\T\\rightarrow \\T$, $i=1,\\ldots,n$ are the delay functions. We are interested about the asymptotic behavior of solutions of mentioned system. More precisely, we formulate conditions on a function $f$, which guarantee that the graph of at least one solution of above mentioned system stays in the prescribed domain. This result generalizes some previous results concerning the asymptotic behavior of solutions of non-delay systems of dynamic equations or of delay dynamic equations. A relevant example is considered."@en . "26220" . "2013" . "RIV/00216305:26220/13:PU106700!RIV14-GA0-26220___" . . . .
