Some mathmetical problems for not beleng to Newtonion floating

This thesis has four sections. In the first section, It is examined important definitions and theorens , equations of motion , conservaton of mass and. Linear momantun. In the second section , it is examined the problem definition and spirad flow etween coaxial cylinders and their properties. In the third section it is counted exact problem solution and calculation of the shear stresses. In the fourth section , it is given the analytical solution of the problem ofnan - linear systems of equations and smilarity of weat solutions.
