Engineering Mathematics Letters, 2014.2049-9337http://hdl.handle.net/20.500.11810/2800In this paper, it is shown that the fixed point theory yields result of best approximation and best approxi-mation yields the variational inequality result. The variational inequality yields fixed point theory. It is also shownthat the fixed point theory is equivalent to maximal elements in mathematical economics. In the end, a couple ofresults are proved extending earlier ones.enFxed pointsVariational inequalityBest approximationMaximal elementsMetric projectionJournal Article, Peer Reviewed
