We prove factorization of the generating functional of connected tree diagrams by exploring that it is the Legendre transform of the action. This theorem is then applied to the example of a local ...

This method defines a system for relating integers to tree structures. An integer can be mapped to two principal types of tree representations, and conversely, a tree structure can be encoded into a ...

Abstract: We study the complexity of traversing tree-shaped workflows whose tasks require large I/O files. Such workflows typically arise in the multifrontal method of sparse matrix factorization. We ...
