Fixed Point Theory for Three �?�?�?��?¢�?�?��?�??Weak Contraction Functions

[摘要] In 2009 Qingnian Zhang and Yisheng Song proved fixed point theory for two φ–weak contraction functions. We generalize this result by finding fixed point and coincidence point for three single-valued φ–weak contraction T1, T2, T3 defined on a complete metric space.
