Let X1, X2, ... Xn be a random variable then.

Weakest

1) lim Fxn(x) = Fx(x) as n -> infiniti (Converges in distribution)

2) lim Pr(|Xn - Xn|>= e) = 0 as n -> infiniti for every e>0. (Converges in probability)

3) Pr(lim Xn = X) = 1 as n -> inifiniti (Converges almost surely)

4) lim Xn(w) = X(w) as n -> infiniti for all w in Omega where Omega is the sample space of the underlying probability space over which the random variable is defined. (Converges Surely)

Strongest

Prove:

If 4 is true then 3, 2 and 1 are true.
If 3 is true then 2 and 1 are true.
If 2 is true then 1 is true.

Convergence and Divergence can rot in hell. I have done my share of this garbage, and have forgotten every smidgen of it. :)

Ughhh.... that brings back nightmares. Last time I tried, yep, tried to deal with that crap was in my first year of college. Didn't used it since.
