Nonoscillation of second-order dynamic equations with several delays. (English) Zbl 1217.34139

Summary: The existence of nonoscillatory solutions for the second-order dynamic equation
\[ (A_0,x^\Delta)^\Delta(t)+\sum_{i\in[1,n]_{\mathbb N}}A_i(t)x(\alpha_i(t))=0\text{ for }t\in [t_0,\infty)_{\mathbb T} \]
is investigated in this paper. The results involve nonoscillation criteria in terms of relevant dynamic and generalized characteristic inequalities, comparison theorems, and explicit nonoscillation and oscillation conditions. This allows us to obtain most known nonoscillation results for second-order delay differential equations in the case \(A_0(t)\equiv 1\) for \(t\in [t_0,\infty)_{\mathbb R}\) and for second-order nondelay difference equations \((\alpha_i(t)=t+1\) for \(t\in [0,\infty)_{\mathbb N})\). Moreover, the general results imply new nonoscillation tests for delay differential equations with arbitrary \(A_0\) and for second-order delay difference equations. Known nonoscillation results for quantum scales can also be deduced.
