### Remark (Bessem Samet, 03 September 2013)

If we denote by beta((x,y),(u,v))=alpha((x,y),(u,v)) if (x,y) is comparable with (u,v) and 0 otherwise, then the condition (3.41) becomes a beta-psi contraction. From the mixed monotone property of F, clearly F is beta-admissible. So it will be more interesting and more general to consider condition (3.41) without order and to obtain the ordered case as an immediate consequence. read full comment

### To Clarify statements of Main Results (Tayyab Kamran, 03 September 2013)

To make the statement of the Theorem 2.4 more clear, please replace the last sentence of Theorem 2.4 by the following sentences.

Then there exists an orbit $\{x_{n}\}$ of $G$ at $x_{0}$ and $x\in X$ such that $\lim_{n\to\infty}x_{n}=x$.
Moreover, $x$ is a fixed point of $G$ if and only if $f(\xi)=d(\xi,G\xi)$ is lower semi-continuous at $x$.

To make the statement of the Theorem 2.9 more clear, please replace the last sentence of Theorem 2.9 by the following sentences.

Then there exists an orbit $\{x_{n}\}$ of $G$ at $x_{0}$ and $x\in X$ such that $\lim_{n\to\infty}x_{n}=x$.
Moreover, $\{x\}=Gx$ if and only if $f(\xi)=\delta(\xi,G\xi)$ is lower semi-continuous at $x$. read full comment

### Print Mistake on the article. (Erdal Karapinar, 03 September 2013)

In Examples 18 and 25, the function F : X X X defined by F(x, y) = 1/8x+5/8y should be
F(x, y) = 1/8x- 5/8y for all x, y to be a mixed g-monotone mapping.

Similarly, in Example 26 [1], the function F : X X X defined by F(x, y) = 1/8x^3+5/8y^3
should be F(x, y) = 1/8x^3-5/8y^3.

We are thankful to Manish Jain to remark this print mistake.

### reference (Nguyen Van Luong, 03 September 2013)

In this paper, the class \Theta and the examples of functions in \Theta are as in the paper "N.V. Luong and N.X. Thuan, Coupled fixed point theorems for mixed monotone mappings and an application to integral equations, Computers and Mathematics with Applications 62(2011), 4238-4248." The inequality of the main result is also as in the paper of Luong and Thuan but in the context of G-metric space.
The authors should cite the paper of Luong and Thuan . read full comment

### An error in hypothesis (Deepesh Kumar Patel, 03 September 2013)

In Corollary 2.2 (Page no. 13) of this paper, an error is occurred. Here the condition g-reciprocal continuity should be removed. read full comment

There is typo in Example 1.6 of our paper entitled Faintly compatible
mappings and common fixed points, $A(x)=x^2$ should be read as $A(x)=x$." read full comment

### On Examples of total quasi-phi-asymptotically nonexpansive mappings. (Farrukh Mukhamedov, 14 May 2012)

The authors need to produce nontrivial exapmles for total quasi-phi-asymptotically nonexpansive mappings, which shoud not be quasi-asymptotically nonexpansive. Otherwise, results are not interesting. For some infomation, certain total asymptotically nonexpansive mappings have been
provided in [F.Mukhamedov, M.Saburov, Jour. Appl. Math. in press. (http://www.hindawi.com/journals/jam/aip/281383). Note that the provided examples are not asymptotically nonexpansive. read full comment
