The term "2+1 dimensional" refers to a system with two spatial dimensions and one time dimension. This concept is relevant in the context of the nonlinear Schrödinger equation, particularly when considering time-dependent external potentials. Such systems can exhibit complex behaviors, including chaotic dynamics, due to the interplay of time and spatial variables. The discussion emphasizes the significance of understanding phase space in these nonlinear systems. Overall, "2+1 dimensional" captures the essence of modeling dynamics in a three-dimensional framework.

what is meant by "2+1 dimensional"

I am assuming this means two space dimensions plus one time...but I just want to make sure.

However, in my case I am working with the nonlinear schrodinger equation with a time dependent external potential. So there is position, velocity, acceleration, and time.

Where? When? By whom?
 


In a paper on the dynamics of the Gross-Pitaevskii equation.

"Time-dependent periodic forces, enriches the behavior of the model. With the explicit time dependence, 2+1 dimensional phase space of the nonlinear system admits the possibility of chaotic dynamics.
 


Yea I think it does... 1 + 1 being lineland.

Yes, that's correct.
 

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
