For a given nonnegative integer number n, we can find a monotone function f depending on n, defined on the interval I=[-1,1], and an absolute constant c>0, satisfying the following relationship: (́) () () (́) , where () is the degree of the best L p monotone approximation of the function f by algebraic polynomial of degree not exceeding n+1. (́) is the degree of the best L p approximation of the functiońbyfunctioń functiońby algebraic polynomial of degree not exceeding n.
