Hi. I don't have a solution, but just an idea. I might break the problem up like this... equ = {alpha[n + 1, j] == Sum[alpha[n, m]*Gamma[c*j - c*m + 1]/Gamma[j - m + 1], {m, n, j - 1}], alpha[0, j] == Gamma[c*j + 1]/Gamma[j + 1]} Then... RecurrenceTable[equ, alpha, {n, 0, Nmax}, {j, n + 1, Nmax + 1}] According to Help, a RecurrenceTable generates a list of values. I may be wrong, but I don't think you can generate values, as both variables c and Nmax are undefined. Perhaps you meant to use RSolve, and then generate a table? = = = = = = = = = = HTH :>) Dana DeLouis Mac & Math 8 = = = = = = = = = = On Apr 6, 6:03 am, Jean <ebegr... at free.fr> wrote: > Hi there, > > I am stuck with the following recurrence problem to solve in Mathematica.
