Abstract. In this paper we generalize and extend Brosowski-Meinardus type results on invariant points from the set of best ap-proximation to the set of best simultaneous approximation, which is not necessarily starshaped. As a consequence some results on best approximation are deduced. The proved results extend and generalize some of the results of R. N. Mukherjee and V. Verm
