They proceed to fully explain the L1 approximation, including bounded variables and plane curves, the Chebyshev approximation
, least squared approximations, and under-determines systems of linear equations.

We suggest instead the use of uniform rational Chebyshev approximations or the application of the trapezoid rule on Talbot-type contours.

n] on R is the solution of the complex Chebyshev approximation problem
Actually, this application, to a certain extent, provided the motivation for the discussion of Chebyshev approximation problems connected via the polynomial mapping [[psi].
It is the solution of the Chebyshev approximation problem
Next, we turn our attention to the computation of optimal polynomials or, more general, to the case of constrained Chebyshev approximation.
