OK, I give up on this one. Can anybody explain me the reason for these
two different outputs?

Many many many thanks in advance!

Andrea


In[304] psi[u_] := LaplaceTransform[Exp[-t], t, u]
           M[u_] := u*psi[u]/(1 - psi[u])
           InverseLaplaceTransform[M[u], u, t]
           InverseLaplaceTransform[FullSimplify[M[u]], u, t]

Out[306] 1/(E^t*2)
Out[307] DiracDelta[t]
