Abstract
Chebyshev-Markov rational functions are the solutions of the following extremal problem
[GRAPHICS]
with K being a compact subset of R and omega(n)(x) being a fixed real polynomial of degree less than n, positive on K.
A parametric representation of Chebyshev-Markov rational functions is found for K = [b(1), b(2)] boolean OR ... boolean OR [b(2p-1), b(2p)], - infinity <b(1) less than or equal to b(2) <...
