A prop structure on partitions
Coline Emprin (ENS, Paris) (online)

Multi zeta values (MZVs) are algebra morphims for some combinatorial products on words. They have a rich algebraic structure and are generalised to trees by the branched zeta values (BZVs). So a natural question is: which of these structures are transferred to BZVs? We will see some elements of answer. In particular, a branched equivalent of the binarisation map will be given.
