A Note on the Oscillation of Second-Order Nonlinear Neutral Functional Differential Equations 1
In this paper, some sufficient conditions for oscillation of secondorder nonlinear neutral functional differential equation [x(t )+ p(t)x(t − τ )] �� + q(t)f (x(t − δ)) = 0 ,t ≥ 0 are established,… Expand
The calculation for characteristic multiplier of Hill's equation x″+q(t)x=0x″+q(t)x=0 in case q(t)q(t) with positive mean
We gave the calculate formula for characteristic multiplier of Hill's equation x″+q(t)x=0x″+q(t)x=0 in case q(t)>0q(t)>0 and q(t) 0.
