SIAM Journal on Numerical Analysis, Vol. 15, No. 3 (Jun., 1978), pp. 612-617 (6 pages) We compare complex or real linear Chebyshev approximation on a compact interval X with approximation on one of ...

We are concerned with the problem of minimizing the supremum norm on an interval of a nonzero polynomial of degree at most n with integer coefficients. This is an old and hard problem that cannot be ...
