An asymptotic result for second order linear nonautonomous neutral delay differential equations (Q987889)

This paper establishes an asymptotic result for the solutions to a second order linear neutral delay differential equations with variable coefficients and constant delays of the form \(x''(t)+c(t)x''(t-\sigma)=a(t)x(t)+b(t)x(t-\tau),\) where \(a, b, c\) are continuous real-valued functions on \([0,\infty)\), and \(\sigma\) and \(\tau\) are positive real constants.
