%X The concepts of relatively weak $R$-subset and class ($W$-)KKM$(X,Y,Z)$ were introduced, an equivalent relation of relative KKM map and relatively weak $R$-subset and a property of $W$-KKM$(X,Y,Z)$ were given; and then two continuous selection theorem were given and from which, fixed point theorems and coincidence theorem were obtained; finally, existence theorems ofalmost fixed point, fixed point theorem and coincidence point theorem for a map with weak-KKM property were obtained on uniform topological spaces.
