Vector fields satisfying the barycenter property

Open Mathematics, 2018
We show that if a vector field X has the C1 robustly barycenter property then it does not have singularities and it is Axiom A without cycles. Moreover, if a generic C1-vector field has the barycenter property then it does not have singularities and it ...

Analysis of the Oscillating Motion of a Solid Body on Vibrating Bearers

Machines, 2019
This article considers the oscillation of a solid body on kinematic foundations, the main elements of which are rolling bearers bounded by high-order surfaces of rotation at horizontal displacement of the foundation.

A tool path patching strategy around singular point in 5-axis ball-end milling

, 2016
In 5-axis high-speed milling, large incoherent movements of rotary axes around the singular point are known to be a problem. Correction methods found in the literature deal mostly with the collision that may happen between the tool and the part but not ...

Equilibrium and Stability of Entropy Operator Model for Migratory Interaction of Regional Systems

Mathematics, 2019
In this paper, we develop a dynamic model for migratory interaction of regional systems that is based on an entropy operator. Next, we study the properties of this operator and establish the existence of a unique singular point in the dynamic entropy ...

SINGULAR POINTS FOR THE SUM OF A SERIES OF EXPONENTIAL MONOMIALS

Проблемы анализа, 2018
A problem of distribution of singular points for sums of series of exponential monomials on the boundary of its convergence domain is studied. The influence of a multiple sequence Λ = {λk, nk}_(∞;k=1) of the series in the presence of singular points on ...
