We obtain via B¨acklund transformation the Hamiltonian representation for a Lax type nonlinear dynamical system hierarchy on a dual space to the Lie algebra
We consider systems of diffusion equations that have considerable interest in Soil Science and Mathematical Biology and focus upon the problem of finding those forms of this class
The Gaussian unitary ensemble with additional symmetry of type ( 3 ) was proposed in the papers [ 1 , 3 ] as an approach to the weak disorder regime in the Anderson model.. In all
We stress that, by following the geometrical interpretation formerly introduced in [ 40 , 41 , 42 ] and generalized in [ 8 , 9 , 23 ], the SW potential is interpreted as
In our previous paper [ 1 ] we found a class of quantum spin 1 2 XZ -type systems on the hyper- cubic lattice Z d with a Gibbsian ground state, characterized by the classical
We present the trigonometric Lax matrix and classical r -matrix for the Kowa- levski gyrostat on so (4) algebra by using the auxiliary matrix algebras so (3 , 2) or sp (4).. Key

Souriau’s construction applied to the two-parameter central extension of the planar Galilei group leads to the “exotic” particle, which has non-commuting position coordinates.. A
