Integrable Hierarchy from Topological Gauge Theory
International Journal of Modern Physics A, 1997By the recursion operator of nonlinear Schrödinger hierarchy, integrable models in 1+1 dimensions are related to the hierarchy of U(1) invariant gauge fixing constraints for the BF gauge theory. The loop algebra structure for the related linear problem with the spectral parameter as a constant valued, zero-strength gauge degree of freedom is derived.

SUPER INTEGRABLE HIERARCHY AND SUPER HAMILTONIAN STRUCTURES ASSOCIATED WITH GUO HIERARCHY
Modern Physics Letters B, 2009A Lie superalgebra is constructed from which establishes an isospectral problems. By solving the zero curvature equation, a resulting super hierarchies of the Guo hierarchy are obtained. By making use of the super identity, the Hamiltonian structures of the above super integrable hierarchies are generated, this method can be used to other ...

Integrability Criterion of Geodesical Equivalence. Hierarchies
Acta Applicandae Mathematica, 1999The subject of geodesically equivalent Riemannian metrics, i.e., metrics with the same geodesic lines, has a long history, beginning with \textit{U. Dini} [Brioschi Ann. (2) III, 269-294 (1870; JFM 02.0622.02)]. Because Riemannian metrics are produced by Hamiltonians in a straightforward manner, it results that the implications of geometry of such ...

Hospital management: Integrating the dual hierarchy?
The International Journal of Health Planning and Management, 1991AbstractTraditionally, hospitals are seen as dual hierarchies: in addition to the formal administrative pyramid, the professional medical system forms a second line of authority. Equally traditional, this poses substantial problems for hospital management.The present study reported in this article took place as part of a larger research project on ...
