 "Onsager's ideal turbulence: Rigidity proofs
    above the threshold and Shnirelmann's
         dissipative solutiuon in 3D" 

In 1949, Lars Onsager wrote the article entitled
´Statistical hydrodynamics´  which appeared in 
Nouvo Cimento. This is the only published work of
Onsager in the field of turbulence. However, his 
insights led him to groundbreaking contributions
to turbulence theory in two and three spatial 
dimensions. In three dimensions, Onsager formulated
a conjecture concerning regularity of incompressible
solutions of Euler equations and the anomalous 
dissipation observed in ideal turbulent flows. 

In this seminar, we continue the review of 'ideal 
turbulence'. Above threshold results of Eyink and
Constantin, Weinan & Titi will be presented. We 
will review in detail the below-threshold 
construction of Shnirelmann. Other particular 
constructions will be also mentioned.
