Abstract:
      In this paper,we investigate the validity of an interesting theorem of Ky Fan 1,Theorem 2] defined on an annulue in infinite-dimensional Banaich space. We prove thatit is true for a condensing mapping under suitable conditions. As applications,some newfixed point are derived,and we also generalize some results of Sun[7,8].
