Turkish Journal of Mathematics and Computer Science, cilt.2026, ss.1-13, 2026 (Scopus, TRDizin)

This paper deals with the behaviors of solutions for nonhomogeneous linear mixed-type (delay and

advance) differential equations. In this study, an asymptotic result and a useful exponential estimate for the solutions

are established. Additionally, stability criteria for the homogeneous equation are also obtained. We obtained these

results using a real root (with a suitable property) of the characteristic equation. We present three examples to

illustrate the hypotheses of these results. We also obtain useful lemmas that give sufficient conditions for the

existence of the roots of the characteristic equation.
