✦ Synopsis
As we know, the Chebyshev weight w(x)=(1&x 2 ) &1Â2 has the property: For each fixed n, the solutions of the extremal problem
dx for every even m are the same. This paper proves that the Chebyshev weight is the only weight having this property (up to a linear transformation).

The L m extremal polynomials in an explicit form with respect to the weights (1&x) &1Â2 (1+x) (m&1)Â2 and (1&x) (m&1)Â2 (1+x) &1Â2 for even m are given. Also, an explicit representation for the Cotes numbers of the corresponding Tura n quadrature formulas and their asymptotic behavior is provided. 1
