Multiple solutions in a boundary value problem
What is it about?
It is about the second order ordinary differential equation with a cubic non-linearity that has a coefficient depending on time and this coefficient is a piece-wise (step) function.
Why is it important?
It provides relatively simple example of a problem that has countable number of solutions. Previously it was believed that this problem has three solutions.
