## Abstract

The purpose of this short note is to present some corrections and clarifications concerning the proof of the main result given in the above mentioned paper.

## Keywords

Concerning the text and the proof of the main result (Theorem 2.2), we would like to do the following corrections and clarifications:

(1) In Theorem 2.2, an additional hypothesis is needed, namely:

(3) On page 5, to prove that the Picard iteration converges to ${x}^{\ast}$, we have to do as follows.

*f*has a unique fixed point (denoted by ${x}^{\ast}$) and the sequence ${({x}_{n})}_{n\in \mathbb{N}}$ converges to a certain $y\in {\bigcap}_{i=1}^{m}{A}_{i}$. We will show that

*y*is also a fixed point of

*f*. For this purpose, we have

This shows that *y* is a fixed point of *f* and, thus, $y={x}^{\ast}$.
