Receiving the approximational constants in apprizal of the velocity of the approaching of functions of class $Lip_M1$ by some methods of summing up the Furie's rows

The suggested work is devoted to the suggested work is devoted to the solution of the problem of receiving precise approximational constants in apprizal of the velocity of the approaching of functions of class $Lip_M1$ by some methods of summing up the Furie's rows. As methods of summing up the Furie's rows are used singular operators like roller up. Un the article 2 methods of soloing this problem are offered.
