1‐independent percolation on ℤ2×Kn
Random Structures &Algorithms, Volume 62, Issue 4, Page 887-910, July 2023., 2023 Abstract A random graph model on a host graph H$$ H $$ is said to be 1‐independent if for every pair of vertex‐disjoint subsets A,B$$ A,B $$ of E(H)$$ E(H) $$, the state of edges (absent or present) in A$$ A $$ is independent of the state of edges in B$$ B $$.

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 102, Issue 9, September 2022., 2022 Abstract This paper is concerned with Kolmogorov's two‐equation model for turbulence in R3$\mathbb {R}^3$ involving the mean velocity u, the pressure p, an average frequency ω>0$\omega >0$, and a mean turbulent kinetic energy k. We consider the system with space‐periodic boundary conditions in a cube Ω=(]0,a[)3$\Omega =({]0,a[}){}^3$, which is a good ...

Computational Intelligence and Neuroscience, Volume 2021, Issue 1, 2021., 2021 This short survey reviews the recent literature on the relationship between the brain structure and its functional dynamics. Imaging techniques such as diffusion tensor imaging (DTI) make it possible to reconstruct axonal fiber tracks and describe the structural connectivity (SC) between brain regions.

On approximation of hypersingular integral operators by bounded ones [PDF]
Journal of Mathematical Analysis and Applications, 2021 We solve the Stechkin problem about approximation of generally speaking unbounded hypersingular integral operators by bounded ones. As a part of the proof, we also solve several related and interesting on their own problems.

Engineering Reports, Volume 2, Issue 2, February 2020., 2020 We have considered a prominent Nonlinear partial differential equation which governs the spatial spread and propagation of mutant genes. A new integral transform called the Elzaki transform was coupled with Homotopy perturbation to solve for the exact solution of this model.

Landau-Kolmogorov type inequalities for curves on Riemannian manifolds
Mathematical Inequalities & Applications, 2019 We obtain Landau-Kolmogorov type inequalities for mappings defined on the whole real axis and taking values in Riemannian manifolds. In terms of an auxiliary convex function, we find conditions under which the boundedness of covariant derivative along ...

Agmon-Kolmogorov inequalities on $\ell^2(\Bbb Z^d)$ [PDF]
, 2013 Landau-Kolmogorov inequalities have been extensively studied on both continuous and discrete domains for an entire century. However, the research is limited to the study of functions and sequences on $\Bbb R$ and $\Bbb Z$, with no equivalent inequalities

A Century of Nonlinearity in the Geosciences
Earth and Space Science, Volume 6, Issue 7, Page 1007-1042, July 2019., 2019 Abstract This paper provides a thumbnail sketch of the evolution of nonlinear ideas in the mathematics and physics of the geosciences, broadly construed, over the last hundred or so years. It emphasizes the mathematical concepts and methods and outlines simple examples of how they were, are, and maybe will be applied to the solid Earth—that is, the ...

Ergodicity of Stochastic Burgers’ System with Dissipative Term
Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013 A 2‐dimensional stochastic Burgers equation with dissipative term perturbed by Wiener noise is considered. The aim is to prove the well‐posedness, existence, and uniqueness of invariant measure as well as strong law of large numbers and convergence to equilibrium.
