evolution equation



An evolution equation is an equation of the form

tf=Lf\partial_t f = L f

where t represents the partial derivative with respect to time, L is a differential operator and f is usually assumed to be an element of some topological vector space. Examples are the Schrödinger equation and the Fokker-Planck equation. These equations describe the time evolution of a physical system, hence the name.
