Limit laws for non-additive probabilities and their frequentist interpretation. (English) Zbl 0921.90005

Summary: We prove several limit laws for non-additive probabilities. In particular, we prove that, under a multiplicative notion of independence and a regularity condition, if the element of a sequence \(\{X_k\}_{k\geq 1}\) are i.i.d. random variables relative to a totally monotone and continuous capacity \(v\), then \[ v\left(\Bigl\{\int X_1dv\leq\lim \inf_n{1 \over n} \sum^n_{k=1} X_k\leq\lim \sup_n {1\over n}\sum^n_{k=1} X_k\leq-\int-X_1 dv\Bigr\} \right)=1. \] Since in the additive case \(\int X_1dv=-\int-X_1dv\), this is an extension of the classic Kolmogorov’s strong law of large numbers to the non-additive case. We argue that this result suggests a frequentist perspective on non-additive probabilities. \(\copyright\) Academic Press.
