✦ Synopsis
In this paper we find some exact values of (n)-widths in the integral metric with the Chebyshev weight function for the classes of functions that are bounded and analytic or harmonic in the interior of the ellipse with foci (\pm 1) and sum of semiaxes
(c). We also construct optimal quadrature formulas for these classes.
