Mathematica

Translation

D[S, {z, 2}]+(Sum[Divide[Subscript[\[Gamma], j],z - Subscript[a, j]], {j, 1, N}, GenerateConditions->None])*Divide[d*S,d*z]+Divide[V[z],Product[z - Subscript[a, j], {j, 1, N}, GenerateConditions->None]]*S == 0

Maple

Translation

diff(S, [z$(2)])+(sum((gamma(j))/(z - a[j]), j = 1..N))*(d*S)/(d*z)+(V(z))/(product(z - a[j], j = 1..N))*S = 0
