Hamiltonian structures on foliations [PDF]
Journal of Mathematical Physics, 2002 We discuss Hamiltonian structures of the Gelfand–Dorfman complex of projectable vector fields and differential forms on a foliated manifold. Such a structure defines a Poisson structure on the algebra of foliated functions, and embeds the given foliation into a larger, generalized foliation with presymplectic leaves.

Second Hamiltonian Cycles in Claw-Free Graphs
Theory and Applications of Graphs, 2015 Sheehan conjectured in 1975 that every Hamiltonian regular simple graph of even degree at least four contains a second Hamiltonian cycle. We prove that most claw-free Hamiltonian graphs with minimum degree at least 3 have a second Hamiltonian cycle and ...

Bifurcation analysis of ion-acoustic waves in an adiabatic trapped electron and warm ion plasma
Journal of Taibah University for Science, 2020 Bifurcation analysis of ion-acoustic waves in complex plasmas in the presence of adiabatic trapped electrons and warm ions is studied. Using bifurcation theory of dynamical structure, the Hamiltonian system inculpated electrostatic potential is derived ...

Stability of Structured Hamiltonian Eigensolvers [PDF]
SIAM Journal on Matrix Analysis and Applications, 2001 This work concerns the stability of structured Hamiltonian eigensolvers. The structured backward errors are defined. By introducing the symplectic quasi-QR factorization, the structured backward errors can be efficiently computed. A detailed rounding error analysis of some Jacobi-like algorithms is also given.

Hamiltonian structures for the Ostrovsky–Vakhnenko equation [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2013 We obtain a bi-Hamiltonian formulation for the Ostrovsky-Vakhnenko equation using its higher order symmetry and a new transformation to the Caudrey-Dodd-Gibbon-Sawada-Kotera equation. Central to this derivation is the relation between Hamiltonian structures when dependent and independent variables are transformed.

Hamiltonian Dynamics in the Theory of Abstraction [PDF]
, 2012 This paper deals with fluid flow dynamics which may be Hamiltonian in nature and yet chaotic.Here we deal with sympletic invariance, canonical transformations and stability of such Hamiltonian flows. As a collection of points move along, it carries along

State maps from integration by parts [PDF]
, 2011 We develop a new approach to the construction of state vectors for linear time-invariant systems described by higher-order differential equations. The basic observation is that the concatenation of two solutions of higher-order differential equations ...
