,Ein Fourier-Algorithmus für die Anfangswertaufgabe der Dreidimensionalen Wirbeltransportgleichung,A Fourier algorithm is given in order to solve the initial value problem to the (suitably modified) equation of transport of vorticity for viscous incompressible fluids in the R.. The algorithm turns out to be stable and convergent with linear convergence velocity. A test problem is elaborated.
