Multicomponent Burgers and KP Hierarchies, and Solutions from a Matrix Linear System [PDF]
, 2008 Via a Cole-Hopf transformation, the multicomponent linear heat hierarchy leads to a multicomponent Burgers hierarchy. We show in particular that any solution of the latter also solves a corresponding multicomponent (potential) KP hierarchy.

Nature, 1998 The now-familiar concept of drawing lines of descent as trees seems harmless enough. But it led Ernst Haeckel (who bent the evidence to prove his Darwinian theories) into believing in the evolution of a Germanic super-race.

Watersheding Hierarchies [PDF]
, 2019 The computation of hierarchies of partitions from the watershed transform is a well-established segmentation technique in mathematical morphology. In this article, we introduce the watersheding operator , which maps any hierarchy into a hierarchical watershed.

Recursion relations for Double Ramification Hierarchies [PDF]
, 2015 In this paper we study various properties of the double ramification hierarchy, an integrable hierarchy of hamiltonian PDEs introduced in [Bur15] using intersection theory of the double ramification cycle in the moduli space of stable curves.

IEEE Transactions on Image Processing, 2018 Superpixel segmentation is becoming ubiquitous in computer vision. In practice, an object can either be represented by a number of segments in finer levels of detail or included in a surrounding region at coarser levels of detail, and thus a superpixel segmentation hierarchy is useful for applications that require different levels of image segmentation

The Toda hierarchy and the KdV hierarchy
, 1995 The Toda hierarchy of size $N$ is well known to be analogous to the KdV hierarchy at $N$ goes to infinity. This paper shows that given $f$ a periodic function, there is a canonical way of defining the initial data for the Toda lattice equations so that ...
