Hyers-Ulam stability for Gegenbauer differential equations

Soon-Mo Jung

Using the power series method, we solve the non-homogeneous Gegenbauer differential equation
 ( 1 - x^2 )y''(x) + n(n-1)y(x) = \sum_{m=0}^\infty a_m x^m.
Also we prove the Hyers-Ulam stability for the Gegenbauer differential equation.
