The more recent version of Mathematica I can access is In[1]:=$Version Out[1]=Linux 3.0 (April 25, 1997) I've to complain with my System Administrator!! Is DSolve so improuved from version 3 to version 4? Can I ask you for a kindness, Paul? Can you check if the following equation DSolve[f''[z]-(z/(1-z^2))f[z]+(a+b/(1-z^2))f[z]==0,f[z],z] can be solved in the more recent version of Mathematica you have? This is not a Legendre equation but it was the problem originally I had, of which I could not find solutions using DSolve of Mathematica 3.0. A last question. If I remember correctly DSolve is a separate program (add-on?. Can I use a more recent version of DSolve without changing the version of Mathematica? Thanks for your time, Nicola Attico. ---------------- Nicola Attico Dip. Fisica - Piazza Torricelli, 2 - Pisa E-Mail: attico at peg2.difi.unipi.it Office: +39 050 911259 Telefax: +39 050 48277
