# Abstract:

## Given a linear eigenvalue problem find all nonlinear equations that are related to it. Associated with a given eigenvalue problem there exists a hierarchy of infinitely many equations. This hierarchy is generated by a certain linear operator. This operator is the squared eigenfunction operator of the underlying linear eigenvalue problem. The operator generating the KdV hierarchy i.e. the squared eigenfunction operator of the Schrodinger eigenvalue problem was found by Lenard. Finding the hierarchy associated with a given equation is equivalent to finding the non-Lie point symmetries of the given equation.
