A new evolution equation [PDF]

open access: yes, 1995
We propose a new evolution equation for the gluon density relevant for the region of small x_B. It generalizes the GLR equation and allows deeper penetration in dense parton systems than the GLR equation does.

Existence of solutions for delay evolution equations with nonlocal conditions

open access: yesOpen Mathematics, 2017
In this paper, we are devoted to study the existence of mild solutions for delay evolution equations with nonlocal conditions. By using tools involving the Kuratowski measure of noncompactness and fixed point theory, we establish some existence results ...

Generalized Mehler Semigroup on White Noise Functionals and White Noise Evolution Equations

open access: yesMathematics, 2020
In this paper, we study a representation of generalized Mehler semigroup in terms of Fourier–Gauss transforms on white noise functionals and then we have an explicit form of the infinitesimal generator of the generalized Mehler semigroup in terms of the ...

Multiscale expansion and integrability properties of the lattice potential KdV equation [PDF]

open access: yes, 2008
We apply the discrete multiscale expansion to the Lax pair and to the first few symmetries of the lattice potential Korteweg-de Vries equation. From these calculations we show that, like the lowest order secularity conditions give a nonlinear Schrödinger

Comments on mesoscopic continuum physics: evolution equation for the distribution function and open questions; pp. 71–74 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2012
In mesoscopic continuum physics it is common to introduce a mesoscopic distribution function. Often also an evolution equation is derived for this distribution function.

Continuum approach to high-cycle fatigue. The finite life-time case with stochastic stress history

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
In this paper, we consider continuum approach for high-cycle fatigue in the case where life-time is finite. The method is based on differential equations and all basic concepts are explained.
