On affine rigidity

open access: yesJournal of Computational Geometry, 2013
We study the properties of affine rigidity of a hypergraph and prove a variety of fundamental results. First, we show that affine rigidity is a generic property (i.e., depends only on the hypergraph, not the particular embedding).

The results of studies of the rigidity of stabilizers and the roll angle of the truck [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета, 2023
Analyzes the change in the body roll angle during curvilinear motion according to the calculation and modeling options in the Matlab&Simulink system. The increase in the values of the required relative to the set angular stiffness of the suspension is ...

Neuromechanical Assessment of Activated vs. Resting Leg Rigidity Using the Pendulum Test Is Associated With a Fall History in People With Parkinson’s Disease

open access: yesFrontiers in Human Neuroscience, 2020
Leg rigidity is associated with frequent falls in people with Parkinson’s disease (PD), suggesting a potential role in functional balance and gait impairments. Changes in the neural state due to secondary tasks, e.g., activation maneuvers, can exacerbate

Onofri inequalities and rigidity results

open access: yesDiscrete & Continuous Dynamical Systems - A, 2017
This paper is devoted to the Moser-Trudinger-Onofri inequality on smooth compact connected Riemannian manifolds. We establish a rigidity result for the Euler-Lagrange equation and deduce an estimate of the optimal constant in the inequality on two-dimensional closed Riemannian manifolds.

A rigidity result for non-local semilinear equations [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2017
We consider a possibly anisotropic integrodifferential semilinear equation, driven by a non-decreasing nonlinearity. We prove that if the solution grows less than the order of the operator at infinity, then it must be affine (possibly constant).
