On the two-boson picture of the KP hierarchy
, 1992 A two-boson realization of the second hamiltonian structure for the KP hierarchy has recently appeared in the literature. Furthermore, it has been claimed that this is also a realization of the hierarchy itself.

Researching Capitalism In Poland: Economic Interests As A Cultural Construction
Journal of Management and Business Administration, Central Europe, 2019 Purpose: The three goals of the article are: first, to show some arguments surrounding the notion of capitalism in theoretical perspective, and also somewhat bashful connotations since it was intro-duced in Poland after the fall of communism; second, to ...

, 2005 We first show that the quasiclassical limit of the squared eigenfunction symmetry constraint of the Sato operator for the mKP hierarchy leads to a reduction of the Sato function for the dispersionless mKP hierarchy.

The (n,1)-Reduced DKP Hierarchy, the String Equation and W Constraints [PDF]
, 2014 The total descendent potential of a simple singularity satisfies the Kac-Wakimoto principal hierarchy. Bakalov and Milanov showed recently that it is also a highest weight vector for the corresponding W-algebra.

Mechanisms for coordinating stakeholders of the higher education market: Theoretical approaches to identification [PDF]
Управленец, 2019 Massive shifts in public relations and enhancing interaction between stakeholders damage the effectiveness of standard coordination models through changing the architecture of business entities’ activity.

International Journal of Foundations of Computer Science, 2002 We propose a new data structure to compute the Delaunay triangulation of a set of points in the plane. It combines good worst case complexity, fast behavior on real data, small memory occupation and the possibility of fully dynamic insertions and deletions. The location structure is organized into several levels.

KP hierarchy and trigonometric Calogero–Moser hierarchy [PDF]
Journal of Mathematical Physics, 2020 We consider trigonometric solutions of the Kadomtsev–Petviashvili (KP) hierarchy. It is known that their poles move as particles of the Calogero–Moser model with trigonometric potential. We show that this correspondence can be extended to the level of hierarchies: the evolution of the poles with respect to the kth hierarchical time of the KP hierarchy ...

"Doubled" generalized Landau-Lifshiz hierarchies and special quasigraded Lie algebras
, 2004 Using special quasigraded Lie algebras we obtain new hierarchies of integrable nonlinear vector equations admitting zero-curvature representations. Among them the most interesting is extension of the generalized Landau-Lifshitz hierarchy which we call ...

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.

PLoS ONE, 2013 Tagging items with descriptive annotations or keywords is a very natural way to compress and highlight information about the properties of the given entity. Over the years several methods have been proposed for extracting a hierarchy between the tags for systems with a "flat", egalitarian organization of the tags, which is very common when the tags ...
