Existence of invariant points and applications to simultaneous approximation
Abstract
For the set of e-simultaneous approximation and e-simultaneous coapproximation, we derive certain Brosowski-Meinardus type invariant point results in this paper. As a consequence, some results on e-approximation, e-coapproximation, best approximation, and best coapproximation are also deduced.
