I've never really liked Mathematica's handling of which functions may be passed assumptions, or may be used (effectively) in Assuming... Assuming[a > 0, Limit[Exp[(-a)*t], t -> Infinity]] 0 Similarly, Assuming[a < 0, Limit[Exp[(a)*t], t -> Infinity]] 0 I can't really answer the question, but I can offer those alternatives to get the assumed limit.
