Multiplicative and semi-multiplicative functions on non-crossing partitions, and relations to cumulants
(Peer reviewed; Journal article, 2023)We consider the group (Ǧ, ∗)of unitized multiplicative functions in the incidence algebra of non-crossing partitions, where “∗” denotes the convolution operation. We introduce a larger group (Ǧ, ∗) of unitized functions ...
