Effect of discreteness on the continuum limit of the Heisenberg spin chain
We discuss the effect of discreteness of the lattice on the classical continuum limit of the isotropic Heisenberg ferromagnetic spin chain, including biquadratic interaction, in the next order. WeExpand

On the integrability aspects of the one-dimensional classical continuum isotropic biquadratic Heisenberg spin chain
The integrability aspects of a classical one‐dimensional continuum isotropic biquadratic Heisenberg spin chain in its continuum limit up to order [O(a4)] in the lattice parameter ‘‘a’’ are studied.Expand

On the integrability of the inhomogeneous spherically symmetric Heisenberg ferromagnet in arbitrary dimensions
The dynamics of an inhomogeneous spherically symmetric continuum Heisenberg ferromagnet in arbitrary (n‐) dimensions is considered. By a known geometrical procedure the spin evolution equationExpand

An extension of a theorem of Nicolaescu on spectral flow and the Maslov index
In this paper we extend a theorem of Nicolaescu on spectral flow and the Maslov index. We do this by studying the manifold of Lagrangian subspaces of a symplectic Hilbert space that are Fredholm withExpand

Cigarette Smoking, Mental Health and Social Support
BackgroundThe prevalence of smoking is high in many Aboriginal Canadian communities; rates of 50% are not uncommon. Aboriginal Canadians suffer a severe burden of smoking-related disease. Research inExpand

The dynamics of diluted Ho Spin Ice Ho2−xYxTi2O7 studied by neutron spin echo spectroscopy
We have studied the spin relaxation in diluted spin ice Ho{sub 2-x} Y{sub x} Ti{sub 2}O{sub 7} by means of neutron spin echo spectroscopy. Remarkably, the geometrical frustration is not relieved byExpand

Neighborhood Deprivation and Maternal Psychological Distress During Pregnancy: A Multilevel Analysis
Maternal psychosocial distress is conceptualized as an important factor underlying the association between neighborhood deprivation and pregnancy outcomes. However, empirical studies to examineExpand

On the evolution of higher dimensional Heisenberg continuum spin systems
We consider the evolution of a classical Heisenberg ferromagnetic spin chain in its continuum limit in higher spatial dimensions. It is shown that the evolution of a radially symmetric chain could beExpand

Soliton damping and energy loss in the classical continuum Heisenberg spin chain
We consider the effect of damping on the evolution of a classical continuum one-dimensional isotropic Heisenberg ferromagnetic spin chain due to relativistic interaction. The correspondingExpand
