Hyers-Ulam Stability Of Nonautonomous Third Order Nonlinear Differential Equations

Hyers-Ulam stability of non-autonomous third order nonlinear differential equations is considered in this paper. This consideration is possible by using the Bihari integral inequality and Gronwall-Bellman-Bihari integral inequality to prove Hyers-Ulam stability and determine Hyers-Ulam constant of every non-autonomous third order nonlinear differential equation considered. Our results improve and extend known results in literature.
