Query: On uniqueness of weak solutions of incompressible Navier-Stokes
  equations in 3-dimensional case   Here we investigate 3-dimensional Navier-Stokes Equations in the
incompressible case with use of different approach and we prove the uniqueness
of the weak solutions for the data from the space, which is dense in usual
space of data. Moreover we study the solvability and uniqueness of the weak
solutions of problems associated with investigation of the main problem.
