Fixed Points of Cone Maps in Locally Convex Spaces

Guo 1] gives some fixed point theorems of cone maps in Banacb space. Here we generalize the main resnlts of 1] to a locally convex space. We remark that the approach in 1] is not applicable in our paper. Throughout this paper. X is a Hausdorff locally convex topological vector space over the field of real numbers, K is a closed convex subset
