No, this was a bug, an inconsistency in handling of assumptions via $Assumptions vs through the Assumptions option: In[1]:= $Assumptions = {k > 0}; In[2]:= Limit[Exp[-k t], t -> Infinity] //InputForm Out[2]//InputForm= Limit[E^(-(k*t)), t -> Infinity] In[3]:= Limit[Exp[-k t], t -> Infinity, Assumptions->$Assumptions] Out[3]= 0 Note that if you avoid the list, everything works. This is already fixed internally, and will appear in a future release. Sorry for the inconvenience. Bhuvanesh, Wolfram Research
