Instead to use here the Langevin equation, we use the more tractable Airault–Malliavin equation, that represents infinite dimen- sional Brownian motion on a current group.. 2 A
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
It is achieved by similarity reduction of equations of the so-called extended discrete KP (edKP) hierarchy [ 18 , 19 , 20 ], which itself is proved to be a basis for construction
properties of orbit functions described in this paper are implications of properties either of orbits of the group W (for description of reflection groups see, for example, [ 17 ] and
In order to ex- plicitly show that those fields constitute the spin-3/2 L supermultiplet, we have to prove an action invariance under appropriate spin-3/2 L SUSY transformations
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
For the generalized DS equations, we showed that the KMV symmetry algebra can be present only if the conditions ( 21 ), under which the symmetry algebra is isomorphic to that of
Using the determinant representation of gauge transformation operator, we have shown that the general form of τ function of the q -KP hierarchy is a q -deformed generalized
