Resumen:
Two fractional Stefan problems are considered by using Riemann-Liouville andCaputo derivatives of order α 2 (0; 1) such that in the limit case (α = 1) bothproblems coincide with the same classical Stefan problem. For the one and theother problem, explicit solutions in terms of the Wright functions are presented.We prove that these solutions are dierent even though they converge, when α % 1,to the same classical solution. This result also shows that some limits are notcommutative when fractional derivatives are used.
