Some common fixed point theorems for four (\psi,\varphi)-weakly contractive mappings satisfying rational expressions in ordered partial metric spaces

The aim of this paper is to prove some common fixed point theorems for four  mappings satisfying (\psi,\varphi)-weak contractions involving rational expressions in ordered partial metric spaces. Our results extend, generalize and improve some well-known results in the literature. Also, we give two examples to illustrate our results.
