Representation of solutions of a second order delay differential equation. <i>Electronic Journal of Differential Equations, 2020</i>(72), pp. 1-20.1072-6691https://hdl.handle.net/10877/14579In this article, we study an inhomogeneous second order delay differential equation on the fractal set ℝαn (0 < α ≤ 1), based on the theory of local calculus. We introduce delay cosine and sine type matrix functions and give their properties on the fractal set. We give the representation of solutions to second order differential equations with pure delay and two delays.Text20 pages1 file (.pdf)enAttribution 4.0 InternationalSecond order delay differential equationsDelayed matrix functionsFractal setArticle
