Finite-Dimensional Hamiltonian Systems from Li Spectral Problem by Symmetry Constraints

Furthermore, using the associated vector fields of the obtained symmetry, we give out the reductions by one-dimensional and two-dimensional subalgebras, and some explicit solutions

The square indicates the fundamental rectangle of the scattering given by the stable and unstable manifold of the outer fixed point.. The shaded area indicates how the

We present a quantitative semiclassical treatment of the effects of bi- furcations on the spectral rigidity and the spectral form factor of a Hamil- tonian quantum system defined by

In addition, we determine the effect of pinned particles on their local environment, and their correlation to critical fluctuations close to the phase transitions.. Another way

A large class of both epidemic and physiologically structured population models with a finite number of states at birth can be cast in the form of a coupled system of non-

In this paper, we develop a Lagrange multiplier method that allows us to analyze adaptive evolution along constraint surfaces of arbitrary dimensionalities in trait spaces of
