Abstract

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