The Mma command DSolve doesn't seem to recognize that the solution to the differential equation, g''[t] - 2*t*g'[t] + w*g[t] == 0 , involves Hermite polynomials. Perhaps I need to inform Mma that w is a non- negative integer. If I let w = 2, for example, then DSolve returns g[t] -> t C - E^(t^2) C + Sqrt[Pi] t C Erfi[t] , which surprised me because I didn't expect the error function in this context. This would be the expected Hermite polynomial if C = 2 and C = 0. Can anyone suggest a better way to proceed?
