Abstract: We study the relationship between the geometry of a real separable Banach space $ B$ (as manifested in its cotype, type, or logtype) and necessary or sufficient criteria for the validity of the Strong Law of Large Numbers (SLLN) for independent $ B$-valued random variables, formulated in terms of the validity of a (verifiable) SLLN for real-valued random variables. Our results are the best possible of their kind and may be used in situations where the SLLN's of Hoffman-Jørgensen and Pisier, and Kuelbs and Zinn are inconclusive.
