Finding the Axis of Revolution of an Algebraic Surface of Revolution

IEEE Transactions on Visualization and Computer Graphics, 2016
We present an algorithm for extracting the axis of revolution from the implicit equation of an algebraic surface of revolution based on three distinct computational methods: factoring the highest order form into quadrics, contracting the tensor of the ...

Dynamics of the Lü System on the Invariant Algebraic Surface and at infinity

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2011
Firstly, the dynamics of the Lu system having an invariant algebraic surface are analyzed. Secondly, by using the Poincare compactification in ℝ3, a global analysis of the system is presented, including the complete description of its dynamic behavior on

On the motive of an algebraic surface.

, 1990
0.1. The theory of motives has been created by Grothendieck in order to understand better — among other things — the underlying "objects" of the cohomology groups and to explain their common properties in the various theories. For instance if the Künneth

The Chen System Having an Invariant Algebraic Surface

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2008
In this paper, we characterize the dynamics of the Chen system ẋ = a(y - x), ẏ = (c - a)x - xz + cy, z = xy - bz which has an invariant algebraic surface.

Reduction of the Singularities of an Algebraic Surface

, 1935
Introduction. The reduction of the singularities of an algebraic surface has been carried out by B. Levi, Chisini, and Albanese.' These reductions are all of an essentially geometric nature, the first two using Cremona transformations of S3 while the ...
