Resumen:
In this short note, we study the behavior of best simultaneousChebyshev approxima-tion by algebraic polynomials on a union ofintervals, when the measure of them tends to zero. We also get aninterpolation result. This results are an extension of the paper [H.H. CUENYA, F.E. LEVIS, A.N. PRIORI, Best simultaneous Lp-approximation on small regions, Numer. Funct. Anal. Optim., 36 (2015), pp. 55-71].
