Submodularity on partitions for forest packing
In order to further develop the theory of packing trees and packing forests in an undirected graph, we extended the notion of supermodular functions on sets to supermodular functions on partitions. This allowed us to prove the augmentation version of the seminal result of Nash-Williams and Tutte, and to extend it to hypergraphs.
