Dear Mathgroup Members, I'd like to clarify my question regarding the Inverse Laplace transform question I raised. I'm actually solving something like this, In[2]:=InverseLaplaceTransform[1/(s^k+a),s,t] Out[2]=\!\(InverseLaplaceTransform[1\/\(a + s\^k\), s, t]\) This is actual mathematica output. Mathematica always returns what I input no matter what value (fractional value between 0 and 1) of k I place, except if you change s^k with Sqrt[s], i.e. k=1/2. If one places k=0.5 it does not work. Is the result for using Sqrt[s] only a formula within mathematica? Anyway, if you have any suggestions on how to solve such a problem, again I'd be very grateful. And sorry about the lack of details earlier. Jaime
