N2  - ABSTRACT: Our aim in the present article is to introduce and study new types of retraction of null helix in Minkowski 3-space.Types of the deformation retracts of the null helix in Minkowski 3-space is presented. The relations between the retraction and the deformation retract of null helix are deduced. Types of minimal retraction of null helix in Minkowski 3-space are also presented. New types of homotopy maps are described.
