For this, α-exponential function which is a kind of functions that play the same role of the classical exponential functions and Laplace transformation formulations of fractional-order derivatives are used. © 2014 Elsevier B.V.falseDelay differential equation | Fractional-order derivative | Fractional-order differential equation | OscillationArticle10.1016/j.cnsns.2014.01.00510.1016/j.cnsns.2014.01.0052-s2.0-84901687096WOS:00033861590000539883993191878-7274
