Bachelor Thesis from the year 2010 in the subject Mathematics - Analysis, grade: 1,0, Technical University of Darmstadt, language: English, abstract: In 1944 Lev D. Landau found a non-trivial solution to a stationary Navier-Stokes flow on R³, which was symmetric around some axis and fulfilled the condition, that the velocity decayed linearlyand the pressure quadratically in |x|, depending on a parameter -1 1. As it turns out, such a modified Landau solution is no longera solution to a Navier-Stokes system - clearly not in the classical, but as well neither in the weak nor veryweak sense. If d = ±1, the velocity will be unbounded on the half line x1 = x2 = 0, ±x3 = 0.In this case, we have a bit more insight in the behaviour of the modified Landau solution, yet still no physically reasonable interpretation can be given in the whole space R³. In any case, one can c
