We consider two problems concerning uniform approximation by weighted rational functions [w n r n ] n=1 , where r n = p n Âq n has real coefficients, deg p n [:n] and deg q n [;n], for given :>0 and ; 0. For w(x) :=e x we show that on any interval [0, a] with a # (0, a^(:, ;)), every real-valued fun
