Given two subsets $A$ and $B$ of a Hilbert space $H$ and the set-valued maps $F:A o 2^ B$ and $G:A_0 o 2^{A_0}$, where $A_0={xin A: |x-y|=d(A,B)~~~mbox{for some}~~~ yin B}$, best proximity pair theorems provide sufficient conditions that ensure the existence of an $x_0in A$ such that $$d(G(x_0),F(x_0))=d(A,B).$$}, keywords = {Best proximity pair,coincidence point,nonexpansive map,Hilbert space}, url = {http://bims.iranjournals.ir/article_381.html}, eprint = {http://bims.iranjournals.ir/article_381_ecee2580be42e5630823af4e23482eb7.pdf} }
