HIGHLIGHTS
- who: Ruipeng Chen from the Department of Mathematics, North Minzu University, Yinchuan, PRChina have published the paper: Positive periodic solutions for multiparameter nonlinear differential systems with delays, in the Journal: (JOURNAL)
SUMMARY
The authors assume that the nonlinear terms f, g ∈ C([0, ∞) × [0, ∞), [0, ∞)) and λ, μ are positive parameters. (C2) There is li > 0 such that 0 and amp;lt; li ≤ gi (s) and amp;lt; ∞, s ∈ [0, ∞). Let σi=e- fying (u, v) ≥ and_(u, v) ≤ q, g * (q) σi i g * (q) 1 - σi i ≤ Gi (t, s) ≤ 1 g (q . . .
