Notes:
The notion of a conserved density is generalized to those densities whose integrals evolve exponentially. In the formal differential algebra used to find them, only a slight modification of the conserved density case is needed. Various examples for quasilinear evolution equations are given and an application to finding higher-order conserved densities by taking the Poisson bracket of exponentially evolving densities is indicated.
