DSolve[(E^x^2 - k^2)*x^3*y[x] - y'[x] + x*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> BesselJ[-k, Sqrt[E^x^2]]*C[1]*Gamma[1 - k] + BesselJ[k, Sqrt[E^x^2]]*C[2]*Gamma[1 + k]}}
Maple raw input
dsolve(x*diff(diff(y(x),x),x)-diff(y(x),x)+x^3*(exp(x^2)-k^2)*y(x) = 0, y(x))
Maple raw output
[y(x) = _C1*BesselJ(k,exp(1/2*x^2))+_C2*BesselY(k,exp(1/2*x^2))]
