Some common fixed point theorems in partial metric spaces

Many problems in pure and applied mathematics reduce to a problem of common fixed point of some self-mapping operators which are defined on metric spaces. one of the generalizations of metric spaces is the partial metric space in which self-distance of points need not to be zero but the property of symmetric and modified version of triangle inequality is satisfied. in this paper,some well-known results on common fixed point are investigated and generalized to the class of partial metric spaces. copyright © 2011 erdal karapnar and uur yksel.
