Contractive conditions introduced in (Q. Zhang and Y. Song, Fixed point theory for generalized φ-weak contraction, Appl. Math. Lett. 22(2009), 75-78) and (D. Đorić, Common fixed point for generalized (ψ, φ)-weak contractions, Applied Mathematics Letters, 22(2009), 1896-1900) are employed to obtain a new common fixed point theorem for four maps. Our result substantially generalizes comparable results in the literature. 2010 Mathematics Subject Classifications. 47H10. .

Keywords: common fixed point, generalized weak contractive condition, weakly compatible maps, lower semicontinous functions
