In this paper we introduced the concept of perfect folding defined on E 2 which equipped by perfect k-coloring of r-monohedral tillings. Then we studied the different cases of perfect foldings of 4-monohedral and 3-monohedral tillings of E 2 . Also the permutations describe each folding are obtained.

In this paper, we introduced the tiling, for closed plane curves α(s), and we discussed the properties of tiling. Also if α(s) was arbitrary plane closed curve equipped by tiling ℑ then we studied the effect of retraction and tiling retraction on it.
THE INVARIANT OF IMMERSIONS UNDER ISOTWIST FOLDING
Mabrouk Salam El-Ghoul,Mohamed Esmail Basher 충청수학회 2005 충청수학회지 Vol.18 No.1
In this paper we will introduce all types of the isotwist foldings of a manifold M into itself. The limits of the isotwist foldings of a manifold are obtained. Also the relations between conditional retraction and this type of the folding are achieved. Finally the variant and invariant of the immersion under the type of folding are deduced.

In this paper, we introduced the tiling, for closed plane curves ${\alpha}(s)$, and we discussed the properties of tiling. Also if ${\alpha}(s)$ was arbitrary plane closed curve equipped by tiling ${\Im}$ then we studied the effect of retraction and tiling retraction on it.

In this paper, we will introduce the isotwist foldings of a manifold M into itself. The limits of the isotwist foldings of a manifold are obtained. Also the relations be-tween conditional retraction and this type of the foldings are achieved. Finally the variant and invariant of the immersion under this type of foldings are deduced.
