Hyers-Ulam stability of linear differential equations of first order Original Research Article

We prove the Hyers-Ulam stability of linear differential equations of first order,(t)y′(t) = y(t). Indeed, this paper deals with a generalization of a paper by Alsina and Ger [1] or of papers by Miura, Takahasi and Choda [2] and by Miura [3].
