Ground states of Heisenberg evolution operator in discrete three-dimensional space-time and quantum discrete BKP equations [PDF]
, 2009 In this paper we consider three-dimensional quantum q-oscillator field theory without spectral parameters. We construct an essentially big set of eigenstates of evolution with unity eigenvalue of discrete time evolution operator.

Concentration Properties of Extremal Parameters in Random Discrete Structures [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 The purpose of this survey is to present recent results concerning concentration properties of extremal parameters of random discrete structures. A main emphasis is placed on the height and maximum degree of several kinds of random trees. We also provide

Discrete breathers in protein structures [PDF]
Physical Biology, 2008 Recently, using a numerical surface cooling approach, we have shown that highly energetic discrete breathers (DB) can form in the stiffest parts of nonlinear network models of large protein structures. In the present study, using an analytical approach, we extend our previous results to low-energy discrete breathers as well as to smaller proteins We ...

Effect of discrete resonant manifold structure on discrete wave turbulence [PDF]
Physical Review E, 2020 We consider the long-term dynamics of nonlinear dispersive waves in a finite periodic domain. The purpose of the work is to show that the statistical properties of the wave field rely critically on the structure of the discrete resonant manifold (DRM).

Epidemic models with discrete state structures
Physica D: Nonlinear Phenomena, 2021 The state of an infectious disease can represent the degree of infectivity of infected individuals, or susceptibility of susceptible individuals, or immunity of recovered individuals, or a combination of these measures. When the disease progression is long such as for HIV, individuals often experience switches among different states.

Two interacting diffusing particles on low-dimensional discrete structures
, 2002 In this paper we study the motion of two particles diffusing on low-dimensional discrete structures in presence of a hard-core repulsive interaction.
