Let ( , ) T a b  be an openinterval of . A (2) C -function 2 :T for tT where, ( ) ( ( ), ( )) t x t y t  is called a parametrized curve(path) on the plane. Let G be a group. Two parametric curves (paths) ()t  and ()t  are called G - equivalentif the equality ( ) ( ) t Ft  is satisfied for an element FG and all tT .
