SUMMARY

The discussion centers on the feasibility of obtaining a surface as a solution from a system of differential equations in a 3D phase space. It is established that the solution of a 3D ordinary differential equation typically results in a curve, although it may be dense on a surface if a conserved quantity is present. The user seeks to formulate a system of three autonomous differential equations based on provided 2D solution plots and is particularly interested in the implications of implicit functions on this process.

PREREQUISITES
  • Understanding of ordinary differential equations (ODEs)
  • Familiarity with phase space concepts
  • Knowledge of autonomous systems in differential equations
  • Experience with implicit functions and their graphical representations
NEXT STEPS
  • Research methods for constructing autonomous systems of differential equations
  • Explore the implications of conserved quantities in phase space
  • Learn techniques for transitioning from 2D solution curves to 3D phase plots
  • Investigate the concept of dense curves on surfaces in differential equations
USEFUL FOR

Mathematicians, physicists, and engineers involved in modeling dynamic systems, particularly those working with differential equations and phase space analysis.

Is it possible for a surface to be obtained as the solution for a system of differential equations in a 3d phase space?
Almost all 3d phase plots I have observed are curves,example the Lorenz system.

Is there a general formula that says that a system of n differential equations would produce a n-dimensional curve in a n-dimensional phase space?

Problem at hand:
I have been provided the individual 2d solution plots for a 3 variable,2 parameter system.Now,with these 2d solution plots,I want to make the 3d phase plot.In the process,I also want to create a system of 3 differential equations.Any suggestions?

The solution of a 3D (ordinary) differential equation is a function from the reals to [itex]\mathbb{R}^3[/itex], in other words a curve (or a fixed point). If there is a conserved quantity, then the solution curve must lie on a surface on which that quantity is constant, but it's still a curve.

It may be possible for the solution curve to be dense on some surface.
 
My problem is a math modelling problem.It is a system of 3 variables and I have been provided 2 solution curve graphs for 1 variable with another.(X vs Y, Y vs Z). I am to now arrive at a 3 eq autonomous system differential equation w.r.t time i.e dX/dt,dY/dt,dZ/dt.
To top all of this complexity,one of my solution graphs is a set of implicit functions(inverse parabola).
So,I would like finally want to arrive at a 3system autonomous d.e and plot the solution curve and hope that it is dense enough to form a surface(another constraint).
I am struggling to go from the solution curves to the autonomous case.Suggestions/helpful keywords in context would help greatly.
