poincare phase plane
They are used extensively to transform complicated behavior in the phase space to discrete maps in a lower-dimensional space. In non-Euclidean geometry the Poincaré half-plane model is the upper half-plane denoted below as H together with a metric the Poincaré metric that makes it a model of two-dimensional hyperbolic geometry.

Experimentally one can perform the phase plane trace at a particular phase z z 0 on a storage oscilloscope Fig. The Poincaré sphere is diffeomorphic to the projective plane mathbf R P 2. It is named after Henri Poincaré but originated with Eugenio Beltrami who used it along with the Klein model and the Poincaré disk model due to Riemann to show that.
Analysis of certain second-order nonlinear systems not easily amenable to the phase-plane methods and described by either of the following differential equations x n-2 fxx 2n gxx n hx0 fxx- n hx0 n0 can be effected easily by drawing the entire portrait of trajectories on a new plane. The path travelled by the point in a solution is called a trajectory of the system. Thats x n 0.

We discuss the boundary in the Poincare phase plane for boundedness of solutions to spring model equations of the form second derivative ofx x epsilonxsuperscript 2 Fcoswt and the second derivative ofx x epsilonxsuperscript 3 Fcoswt and report the results of a systematic numerical investigation on the global stability of solutions to initial value problems. He has served as lead engineer for Tube Lines Ltd. The method yieldsaccurateestimates ofbifurcationpointsoutof experimental data.
X2 y2 z2 1 where z Z1 with the diametrically opposite points identified which is considered without its equator E and an infinitely remote straight line of a plane R2x y. For Poincare planes is described in Sec. After that the responses of the system are solved numerically using the Newmark-β method and bifurcation diagram three-dimensional spectral plots.
Unfortunately this nearly always results in numerical work since analytic solutions can rarely be found. 29 April 1854 Nancy Lorraine France Died 17 July 1912 Paris France Summary Henri Poincaré can be said to have been the originator of algebraic topology and of the theory of analytic functions of several complex variables. In non-Euclidean geometry the Poincaré half-plane model is the upper half-plane denoted below as H together with a metric the Poincaré metric that makes it a model of two-dimensional hyperbolic geometry.

That is on one of the x n x planes. He has served as. We think of this as describing the motion of a point in the plane which in this context is called the phase plane with the independent variable as time.
Equivalently the Poincaré half-plane model is sometimes described as a complex plane where the imaginary part the y coordinate mentioned above is positive.
