Description
The solution operator of many PDEs generates infinite-dimensional dynamical
systems. However, numerical algorithms approximating solutions of such PDEs
are inherently finite dimensional. Work suggesting numerical schemes can
capture the correct dynamics of the infinite-dimensional systems they
approximate, provided the space and time mesh are sufficiently refined,
will be presented. The theory is applied to the Navier-Stokes equations,
and estimates on the resolution required of the numerical scheme are also
given.
