Her research during this time focused on the electronic and optical properties of two-dimensional systems.

One important implication is that a two-dimensional continuous dynamical system cannot give rise to a strange attractor.

The Morris-Lecar model is a two-dimensional system of nonlinear differential equations.

The airfoil model is then reduced to a simpler two-dimensional system.

In certain two-dimensional systems, mixed symmetry can occur.

The two-dimensional systems can exist in negative temperature states.

A discrete linear two-dimensional system is often described by a partial difference equation in the form:

Consider a two-dimensional system of non-interacting particles with charge and spin confined to an area in the x-y plane.

A two-dimensional system of linear differential equations can be written in the form:

The equation can be transformed into an equivalent two-dimensional system of ordinary differential equations.
