Resumen

In this paper we obtain the condition for the existence of Ricci solitons in non-flat generalized complex space form by using Eisenhart problem. Also it is proved that if (g, V, λ) is Ricci soliton then V is solenoidal if and only if it is shrinking or steady or expanding depending upon the sign of scalar curvature.
