Kovalevskaya on chaos
Functions of space can allow us to change how a PDE solution varies in space and time. This page explores an example using an image of Sofya Kovalevskaya encoded as the function $I_S(x,y)$. The system uses the complex Ginzburg–Landau equation.

You can upload your own image by clicking on and then clicking on the image of Sofya Kovalevskaya’s face next to $I_S(x,y)$. The image will be effectively treated as a greyscale function $I_T(x,y)$, which will be approximately 1 when the image is close to white and approximately 0 when the image is close to black. → Images

Change $I_T$ to $I_S$ in to see another famous mathematical face: → Definitions Alan Turing.
-
You can upload a replacement for either of these images under They can each be used as heterogeneities in many parts of VisualPDE. → Images.
