Fixed point theorems for generalized multivalued mappings in cone metric spaces

In this paper, we prove some fixed point theorems for generalizedmultivalued mappings by using the c-distance recently introduced byCho, Saadati and Wang [Y.J. Cho, R. Saadati and S.H. Wang, Commonfixed point theorems on generalized distance in ordered cone metricspaces, Comput. Math. Appl. 61 (2011), 1254-1260].Our results improve and generalize the correspond ones of ′Ciri′c [6],Feng and Liu [7], Kim and Wardowshi [13], Latif and Abdou [14], Mizoguchiand Takahashi [16].
