| Abstract: |
| This paper deals with Hyers-Ulam stability (HUS) of first and second order linear differential equations with periodic coefficients. Necessary and sufficient conditions are established for Hyers-Ulam stability of the linear differential equations by means of the constant variation method. The related results of Hyers-Ulam stability for first order homogeneous linear differential equations with periodic coefficients are generalized. |
