Abstract
In 1969, Boyd and Wong proved a fixed point result for single-valued contractions, that was extended by Reich in 1972, to multifunctions with compact values. Reich then asked whether the result holds for multifunctions with closed, bounded values, which is known as Reich’s conjecture. Using a simple variational approach, we give in this note a partial positive answer to the conjecture, which contains the previous related contributions.
