quadruple fixed point of multivalued nonlinear contraction mappings

The notion of Quadruple fixed point is introduced by Karapinar E. [6]. Samet and Vetro [12] established some coupled fixed point theorems for multivalued non linear contraction mapping in partially ordered metric spaces. In this paper, we obtain existence of quadrupled fixed point of multivalued nonlinear contraction mappings in framework work of partially ordered metric spaces. Also, we give an example.
