[itex]\frac{\partial{a_0}}{\partial{x}}\frac{\partial{a_1}}{\partial{y}}-\frac{\partial{a_0}}{\partial{y}}\frac{\partial{a_1}}{\partial{x}}=0.[/itex]

with both functions depending on x and y.

I am quite sure I have seen equations of this form before but I do not remember when and where. Maybe someone of you guys can help me?

Thanks
