Weak contractions are generalizations of the Banach's <br />contraction mapping, which have been studied by several authors. In <br />this paper, we introduce the notion of $f$-weak contractions and <br />also establish a coincidence and common fixed point result for <br />$f$-weak contractions in cone metric spaces. Our result is supported <br />by an example which include and generalize the results of Choudhury <br />and Metiya's work.http://bims.iranjournals.ir/article_218_d595625aa45af7f415864e2b1458807a.pdf
