Boundary De Giorgi-Ladyzhenskaya classes and their application to   regularity of swirl of Navier-Stokes
  The embeddings theorem of space-boundary-type DeGiorgi-Ladyzhenskaya parabolic classes into Holder spaces is presented, which is useful for regularity considerations for parabolic boundary value problems. Additionaly, the application of this theory to Navier-Stokes-s swirl is presented.
