The visual boundary of hyperbolic free-by-cyclic groups

open access: yes, 2018
Let $\phi$ be an atoroidal outer automorphism of the free group $F_n$. We study the Gromov boundary of the hyperbolic group $G_{\phi} = F_n \rtimes_{\phi} \mathbb{Z}$. We explicitly describe a family of embeddings of the complete bipartite graph $K_{3,3}$

Geometric Estimates in the Polynomial Interpolation

open access: yesМоделирование и анализ информационных систем, 2011
We prove some new inequalities for the norms of projections due to the polynomial interpolation of continuous functions of n variables.

On a class of exact locally conformal cosymlectic manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
An almost cosymplectic manifold M is a (2m+1)-dimensional oriented Riemannian manifold endowed with a 2-form Ω of rank 2m, a 1-form η such that Ωm Λ η≠0 and a vector field ξ satisfying iξΩ=0 and η(ξ)=1. Particular cases were considered in [3] and [6].

On the Lassak Conjecture for a Convex Body

open access: yesМоделирование и анализ информационных систем, 2011
In 1993 M. Lassak formulated (in the equivalent form) the following conjecture. If we can inscribe a translate of the cube $[0,1]^n$ into a convex body $C \subset R^n$, then $\sum_{i=1}^n \frac{1}{\omega_i} \geq 1$. Here $\omega_i$ denotes the width of $

Scaling Behavior and Phases of Nonlinear Sigma Model on Real Stiefel Manifolds Near Two Dimensions

open access: yesUniverse
For a quasi-two-dimensional nonlinear sigma model on the real Stiefel manifolds with a generalized (anisotropic) metric, the equations of a two-charge renormalization group (RG) for the homothety and anisotropy of the metric as effective couplings are ...

Multi-scale measurement of constitutive viscoelastic properties of bituminous composites considering moisture and deicing conditions

open access: yesCase Studies in Construction Materials
The use of salt and chemical deicers can cause significant damage to road infrastructures. This study investigates the impact of different deicers on the viscoelastic properties of mastic and asphalt mixtures, with a focus on characterizing their ...
