Abstract:	In this paper we prove that $d_n = d^n = delta _n = left\| {Ax^circ } right\|_p$ (1o and the optimal subspace for n-width d_n in space X=l _n ^N . Where d_n in the n-width, in the sense of Kolmogorov, ofD in X, dⁿ is the n-width ofD with respect to X, in the sense of Gel'fand, δ is the linear n-width ofD with respect to X.
