Resumen de Best simultaneous approximation on small regions by rational functions.

Hector H. Cuenya, Fabian E. Levis, A.N. Priori

• We study the behavior of best simultaneous (lq,Lp)-approximation by rational functions on an interval, when the measure tends to zero. In addition, we consider the case of polynomial approximation on a finite union of intervals. We also get an interpolation result.
