(T, L) Semi - Homotopy and (T, L) semi - Isotopy

Abstract

In this work we present the definitions of (T,L) semi a– homotopy (T,L), strongly semi - a homotopy and we give the relation among them and (T,L) homotopy , (T,L) a- homotopy (T,L) semi homotopy , (T,L) strongly a - homotopy , also we present the definition of (T,L) semi a - isotropy , (T,L) strongly semi a - isotopy and we study the relation awong them and (T,L) isotopy , (T,L) a - isotopy, (T,L) strongly a - isotopy and (T,L) semi isotopy .

Several Characterization of these concepts.
