Invariant Points and ε-Simultaneous Approximation

الملخص EN

We generalize and extend Brosowski-Meinardus type results on invariant points from the set of best approximation to the set of ε-simultaneous approximation.

As a consequence some results on ε-approximation and best approximation are also deduced.

The results proved in this paper generalize and extend some of the known results on the subject.
