ON THE THEORY OF BRAID GROUPS

Russian Academy of Sciences. Sbornik Mathematics, 1993
Let \(V\) be a set of (finite) words in an alphabet of variables ranging over elements of a group \(G\). The subgroup \(V(G)\) of the group \(G\) generated by all values of words from \(V\) is called the verbal subgroup defined by the set \(V\). The width of the subgroup \(V(G)\) is defined to be the minimal number \(m \in \mathbb{N} \cup \{+\infty\}\)

A Theory of Bayesian Groups

Noûs, 2017
AbstractA group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever ...
