what is meant by "2+1 dimensional"

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.
